If it helps anyone this is a sample of a weeks food in our house,
Sunday - roast chicken (large one from the market)
I build out roasts but giving a small amount of Meat and loads of veg and potatoes, a mixture is sewer potato and regular, roast squash when it's in season, seasonal greens steamed with some garlic, carrots, broccoli, sprouts, tinned sweetcorn or frozen peas. If I've made pancakes for breakfast I'll use the remaining batter and make Yorkies and gravy from chicken roasting tin juices.
Next day any left over veg and half the left over chicken goes into a white sauce made with stock instead of milk, a big tbsp of mustard and salt and Pepper, it's covered with a brought puff pastry sheet and put in the oven until it's golden. Served with whatever veggies are in int he freezer. This is my family's favourite meal.
The rest of the chicken is then chicken in hone soup maker with the sad looking celery, onion and carrot from the fridge drawer and if I've got a tin of chick pea shoe beans I'll use them too in the soup maker to make lunch for ds3 and me for the next 2-3 days.
The carcass of the clean is then boiled up to make stock and I use that for a veggie risotto in day 3 for dinner.
Day 4 (wed) I'll whizz up veggies and herbs to make pasta sauce, usually I'll make the pasta but I have issue using dried if I'm out of time/energy. A sprinkle of grated cheese and a side salad to make dinner.
Day 5 - left over pasta sauce will top a homemade pizza base from the freezer, with a value ball of mozzarella and any left over meat/peppers/mushrooms/sweetcorn we have in the fridge, served again with a large side salad and occasionally garlic bread if I've got any in the freezer that I've batch cooked previously.
Day 6 (Friday) large veggie curry, made in the SlowCooker with beef stock cube to give it a meaty flavour. I serve with rice then leave enough rice for leftovers. We'll have left over curry on a jackets for Sat lunch,
Day 7 (Sat) - for dinner I'll use the leftover rice to make a big salad with boiled eggs diced pepper, peas, sweetcorn and some tuna if I have a tin. Served with crust bread and salad.
It's a fairly cheap menu and they are big portions.
I buy a tray of 15 eggs and boil them all at once for healthy snacks, I also make hummus from tinned chickpeas and keep some chopped up carrot sticks in the fridge for snacks.
I bake once a fortnight and I do 5-6 lots of tray bakes, flapjacks, muffins etc to keep in hone house, nothing fancy or expensive though!
I do grow salad leaves, because they come back one you cut them and we get some cheap tomato plants to grow in the garden in a grow bag in hone sun. They cost £50 from the farm shop and produce hundreds of tomatoes.
I buy flour in bulk packets from Makro but they do them on Amazon (although I know it's frowned upon) I buy yeast/flour and mixed seeds in I bulk so I can make a daily loaf of bread minus the chemicals, I find it relaxing to sit and knead it and it tasted 19x better than shop loaves and it never goes mouldy because it's being used daily.
DP makes peanut butter as we eat a lot of it, he uses bulk bought lightly salted peanuts from Makro again though you don't have to use bulk ones, Aldi so bags of them fairly cheap and there is no other ingredient, it's just sticking them in a food processor and letting them go until you have a peanut butter consistency.
