Meal prep for beginners is three steps, not thirty: cook one protein in bulk, one carbohydrate in bulk, and two trays of vegetables. Ninety minutes on a Sunday covers five weekday lunches. Mr PT Fitness is a private home studio at 35 McIntosh Road, Dee Why, run by Matt Reilly, a personal trainer with 10+ years' experience, and this is the prep system we give clients who work full time and have no interest in becoming a weekend chef. You are not cooking twenty-one meals. You are cooking components and assembling them in four minutes on a Tuesday.
Why does meal prep make eating well automatic?
Meal prep works because it moves the decision from 12:30pm, when you are hungry and busy, to Sunday afternoon, when you are neither. The food you eat at lunch on Wednesday is decided by what was in the fridge on Sunday, not by willpower at the time.
Most people do not eat badly because they lack knowledge. They eat badly because at 12:30 the fastest available option is the one that wins, and at 6:45pm after a commute back to Dee Why the fastest option wins again. Prep changes which option is fastest.
This is the same mechanism behind every habit that holds. You change the environment once and the behaviour follows, rather than negotiating with yourself daily. It is worth reading alongside protein at every meal, because prepped food only helps if the thing you prepped is worth eating.
There is a second effect that is easy to miss. Prepped food removes the 4pm decision spiral where you know dinner is unplanned, so you snack to bridge the gap, then eat dinner anyway. That gap is where a lot of extra food quietly lives.
What is the 3-step system?
Cook one protein, one carbohydrate and two vegetable trays in bulk, keep them in separate containers, and combine them differently each day. Separating the components is the part that stops prep feeling like eating the same meal five times.
Full assembled meals, the ones portioned into identical containers on Sunday, look better in photos and get abandoned faster. Component prep gives you the same time saving with a different plate each day.
| Step | What to cook | Amount for 5 meals | Method |
|---|---|---|---|
| 1. Protein | Chicken thighs, beef mince, salmon, eggs or tinned legumes | 1.2kg to 1.5kg raw | Oven tray at 200 degrees, 25 to 35 minutes |
| 2. Carbohydrate | Rice, pasta, potatoes, couscous | 500g dry, about 1.4kg cooked | One large pot while the oven runs |
| 3. Vegetables | Any two of pumpkin, broccoli, capsicum, zucchini, carrot | Two full oven trays | Roast with the protein, or steam in 8 minutes |
That is the whole system. A palm-sized protein serve, a fist of carbohydrate and two handfuls of vegetables per container, which is the portion structure we use in the 1-on-1 sessions from $50 listed under services.
Week one, prep weekday lunches only. Five meals. People who try to prep every meal in their first week almost always stop by week three, because they have built a system that needs three hours instead of ninety minutes.

What does a 90-minute Sunday prep look like?
Roughly 15 minutes of setup, 45 minutes of oven time you spend elsewhere, and 20 minutes of portioning and cleaning. Hands-on time is closer to 35 minutes, which is why the oven does most of the work in this system.
- 0 to 10 minutes: oven to 200 degrees. Protein on one tray, vegetables on two more. Oil, salt, pepper, whatever spice mix you like.
- 10 to 15 minutes: trays in. Rice or pasta pot on the stove, timer set.
- 15 to 45 minutes: leave the kitchen. This is the part people skip, and it is why prep feels like it takes half a day when it does not.
- 45 to 60 minutes: everything out, spread it wide on trays so it cools quickly rather than sitting warm in a deep container.
- 60 to 80 minutes: portion into containers once cooled, label the lids with the day you cooked, fridge the first four days and freeze the rest.
- 80 to 90 minutes: clean up. Two trays and a pot.
The order matters more than the recipe. Oven first, stove second, cooling third, portioning last, because the cooling step is the one that sets how safe and how good the food is on Thursday.
If ninety minutes on Sunday is not realistic, split it. Protein on Sunday night, vegetables on Tuesday night while dinner cooks. Two forty-minute sessions work as well as one long one, and they survive a busy weekend better.
How do you stop prepped food getting boring?
Change the sauce, not the recipe. The same chicken, rice and vegetables becomes five different meals with five different finishes, and each one costs under a minute. New recipes are what make prep collapse, because each one adds shopping, reading and washing up.
- Monday: soy, sesame, chilli flakes.
- Tuesday: Greek yoghurt, lemon, garlic, cracked pepper.
- Wednesday: pesto stirred through the rice.
- Thursday: harissa or sriracha with a squeeze of lime.
- Friday: curry paste and a splash of coconut milk, heated in the pan for two minutes.
Texture is the other lever, and it is the one most people forget. Something raw and crunchy added at the plate, such as cucumber, spinach or a handful of nuts, changes a reheated container into something that eats like a fresh meal.
Worth checking the labels on the sauces you lean on, since some sit high in sugar and sodium per 100g. That takes twenty seconds using the method in how to read a nutrition label, and it is not a reason to avoid sauces. A tablespoon of something you enjoy is what keeps the whole system running for months.
Rotate the protein monthly rather than weekly. Chicken for four weeks, then beef mince for four weeks, is a change you will actually notice, while changing it every week means relearning cook times constantly.
How long does prepped food last, and how should you store it?
Cooked food keeps three to four days in a fridge at or below 5 degrees, and about three months in the freezer. Cool it within two hours of cooking, store it in shallow containers, and reheat it until it is steaming hot right through.
The two-hour rule is the one worth remembering in a Sydney summer. Food left sitting on the bench to cool for three hours has spent that time in the temperature range where bacteria multiply fastest, and reheating it later does not undo that.
| Food | Fridge (at or below 5 degrees) | Freezer |
|---|---|---|
| Cooked chicken, beef, pork | 3 to 4 days | About 3 months |
| Cooked fish | 2 to 3 days | About 3 months |
| Cooked rice and pasta | 3 days, cooled fast and refrigerated | About 1 month |
| Roast vegetables | 3 to 4 days | Texture suffers, not recommended |
| Hard-boiled eggs in shell | Up to 7 days | Not suitable |
Cooked rice deserves its own line. Cool it quickly, refrigerate it within an hour where you can, and do not leave it at room temperature overnight, because rice is the prepped food most often involved in home food poisoning.
Practical version: containers with the cook date on the lid, the first four days in the fridge, day five onwards in the freezer from day one. When in doubt, throw it out, which costs a few dollars and is cheaper than a lost training week.

Frequently asked questions
How do I start meal prepping?
Start with one protein, one carbohydrate and two vegetables, cooked in bulk on a Sunday. Do not try to prep every meal in week one. Cover weekday lunches only, which is five meals, and add dinners once the routine holds. That first session takes about 90 minutes.
How long does prepped food last?
Cooked meat, rice and pasta keep three to four days in the fridge at or below 5 degrees. Cool them within two hours, then refrigerate in shallow containers. Anything you will not eat by day four goes into the freezer on day one, where it keeps for about three months.
Is meal prep cheaper?
Usually yes, because you buy larger cuts, use what you buy, and stop paying for weekday lunches out. A $16 bought lunch five days a week is $80. The same five meals prepped at home sit closer to $30 to $40, depending on which protein you choose.
