Chicken wings have quite a bit of meat on and can be turned into risotto or stir fry.
Of all the crazy things I’ve read on MN food threads, this has to be the craziest. A chicken has two wings. You’d get no more than 4 or 5 tbsp of flesh from two roasted chicken wings, even if the chicken is large, and that’s if you’re really, really careful. Turning that into a risotto or stir fry for 2 people (one chicken wing each, that is) is totally inefficient.
Cooking in a budget is about getting max calories and nutrition from as little money as possible. So less but enough high fat, high fibre, high carb food, coupled with cheaper but nutritious vegetables.
I’d do a slow cooked stew: cheap cuts of mutton or beef, trimmed but not entirely so. Stock cube and water. Lots of carrots, celery, onion, seasoning. Add lentils and potatoes. If you can stretch to it, sprinkle grated cheese on top and eat with a slice of bread.
Brown rice with chick pea curry and plain yogurt. All inexpensive base ingredients.
If you’re going to roast a chicken, leave the skin on and smear some butter between the skin and flesh. Eat less of it (because high calorie) and plenty of vegetables and boiled potatoes. Use the rest of the chicken to make chicken soup or pie, chicken salad with jacket potatoes, cold cut platter with bread and butter and tomatoes/cucumber, chop into pasta sauce etc.
Don’t be afraid of cheaper desserts like pre made custard or ice cream on top of sliced oranges. If it’s just for a few weeks neither of you will be nutritionally harmed by it.
