It's not actually soul destroying, though. It's a grind and takes a lot of thought and work but, once you get into the swing of it and adjust expectations it's not that bad.
I used to cook 2lbs of dried beans on a Sunday and then use them in different things all week. Obviously, it depended on the type of beans but an example would be pinto beans.
1, rice, beans and greens
2, bean burgers with wedges
3, refried bean quesadillas
4, bean chilli
5, bean and ham soup
Then the other two nights would be some kind of pasta thing and some kind of potato thing.
Or, using the same 7 ingredients
1, cauliflower and bacon soup with crusty bread (hm)
2 potato, onion and bacon bake with carrots
3, macaroni cheese with cauliflower
4, baked potatoes with cheese, onion and grated carrots
5, mixed veg curry made from whatever cauli, onions, carrots and potatoes are left.
Breakfast would be things like porridge, hm pancakes or breakfast muffins, toast and peanut butter with banana, other baked things.
Lunch would be leftovers, hm soup, sandwiches, tomato rice, creamed tuna rice and peas, caramelized onion pasta.
Snacks were either basic fruit or things I made like potato cakes, garlic bread sticks or yoghurt loaf.
As I say, a lot of work, a lot of planning but everyone was fed, nourished and happy.
