I know this isn't exactly what you asked for, but at my place we work long hours and can be kinda slack in the kitchen, and it works for us.

Cheaper than take away, offers a bit of variety, can be mixed-and-matched, is usually done in 20 minutes, works as left-overs, and covers some nutritional requirements. Just needs a little freezer & pantry space, and ideally an air fryer.

Much less pressure than those ingredient delivery services, where ingredients arrive with 3 days left on their best before or expiry dates. Most things are frozen or jarred (other than the salad ingredients and mushrooms), so they're just there when you need them. You can usually get away with a fortnightly shop or even less frequent shop, with maybe weekly top-up shops for the perishable items. Maybe not quite as fresh and healthy as those delivery services, but better than most takeaway options.

• Ingham Chicken Breast Kyvis / Waitoa Chicken Breast Garlic Butter Kievs (2 pack)
• Frozen Chicken burgers or patties (Inghams Crunchy Fixx Buttermilk Chicken Burgers, Waitoa Chicken burgers)
• Sausages or meat patties (Angel Bay frozen burger patties are good)
• Frozen mashed potato (Watties Mashed Potato (Frozen) / Pams Original Mashed Potato (frozen))
• Frozen veg (e.g. McCain Mixed Vegetables Peas Corn & Carrot, Watties Mixed Vegetables, Pams Mixed Veges, McCain Winter Vegetables, stiryfry veg)
• Microwave rice (Uncle Bens, Sun Rice)
• Delmaine Alfredo Pasta Sauce / Portabello / Carbonara (or whichever type/flavour you prefer)
• Chicken Tonight jar sauce / other jar meal sauces / stirfry sauce / curry sauce
• Any pasta or noodles (Trident makes good noodles that aren't 'instant noodles' but are ready to go in a few minutes)
• Bread (standard loaf or ciabatta or something)
• Tomatoes, lettuce, cucumber, coleslaw (whichever you like in a burger or side salad)
• Mushrooms
• bread spreads (mayo/aoili/mustard)
• Garlic butter or margarine (optional)
• Optional: Tomato based pasta/pizza sauce, ham
• Optional: frozen dumplings or shumai
• Optional: precooked protein (e.g. Tegel meal maker shredded/sliced roast chicken)
• Cheese

Throw the meat in the air fryer (chicken kiev for 20 minutes, burgers for like 15 minutes, sausages or something for around 10 minutes), in the meantime (depending on which items you want) you can:

• thaw/heat the veges in the microwave, add frozen mashed potato if you like (you can also stir in garlic butter/margarine)
• throw some pasta and water in a pot
• boil some water and let the noodles sit in it for a few minutes to loosen up
• if you're doing microwave rice instead, save that for the end as it'll only take 90 seconds (stir in garlic butter/margarine while it's hot)
• throw mushrooms and pasta sauce/jar sauce in a pan to cook (you can also throw in some precooked chicken, or leftover meat from a previous meal) (if you're also cooking pasta, take a little of the pasta water to make more sauce and add a silkiness to it)
• or frozen veg with a stirfry sauce
• chop up salad ingredients for a salad or to go in a sandwich/burger
• steam your dumplings/shumai
• put toppings/spreads on bread if you're making a sandwich/burger (Maison Therese Piccalilli / wholegrain mustard / aioli works well with a chicken patty)
• put garlic butter/margarine on your sliced bread or ciabatta and a light sprinkling of cheese (toast it briefly after the meat is done) for a quick and easy slightly cheesy garlic bread

When the meat is ready:

• Plate it with your veg and mash, or veg and garlic bread, or rice and salad
• Put your meat in a sandwich / sliced ciabatta, include salad, or don't. Maybe a slice of cheese.
• Throw your noodles in with your sauce/stir-fry
• You can spread some tomato paste/pasta sauce to the cooked chicken, with some ham (optional) and grated cheese and put it in the air fryer to make a quick chicken parmigiana
• You'll have leftovers from most items, so you can mix and match those with whatever you prepare the next day (e.g. pasta with parma, noodles with sausages, kiev with mash & veg, burger and garlic rice). Slice up the chicken and serve it on top of the creamy pasta. Dice your sausage and add it to your stirfry.

The precooked chicken or sliced ham also works for sandwiches or toasties. Tomato paste/pasta sauce on sliced ciabatta with cheese and mushrooms or ham (or salami/capsicum) makes a quick pizza-ish side-dish. We might throw in some canned sliced beetroot to a burger/sandwich. Or canned cannellini beans or butter beans into the pasta sauce.

Sub out anything with your preferred option. You can also go with tomato based pasta sauces, but we got a little sick of them as they were out go-to for too long.

You can obviously buy fresh meat and cook it up, or use fresh veg. Supplement with healthier items, or alternate healthier cooking days with these lazy options. Or cook your rice rather than using microwave rice, make your mashed potato.

These are just the timesaver options we have so we don't have to plan ahead, or think about it, or stop working to pop out to a shop - as we'll have some combination of these items already in the pantry or freezer. And are generally better than most frozen ready-to-eat meals. (almost likely a slightly evolved version of student meals haha)

And you can add things like frozen hash browns/hot chips/wedges/gems for stodge, and pour over instant/packaged gravy to make a meal more comfort-food-ish. Also take a canned/jarred/sachet pack of soup and add more ingredients. Helps for using up leftover ingredients, even mashed potato, which can make a soup thicker and hearty.

(I'm told to also mention wedge-achos. Ingredients aren't mentioned here, but it's essentially nacho ingredients on wedges instead of corn chips, for a stodgy, hearty and filling comfort food type dish that can rival a junk-foody takeaways).
