Apart from freezing requirement medjera meets the cheap, quick, delicious standards. It's an onion rice lentilly affair- I follow the ottolenghi recipe but a google will throw up loads. It really is lovely.
Another for me would be spinach and red lentil dhal, with flatbreads.
it's also the season for soup- minestrone, scotch broth, cawl, pumpkin ( really cheap for the next month or so ) chicken, leek and potato, broccoli and blue cheese, Han and pea, country veg, lentil and chickpea, endless varieties. With a good slice of bread soup is a meal many a night in chez pause. And most can be frozen for later.
Sausage casserole, made with onions, mushrooms, celery, carrots, stock and tin toms- flavoured with garlic and herbs is cheap and freezable, just make some chips mash to go with it when eating, or stir in pasta shapes and call it a sausage ragu instead of casserole. Or add a tin or two of mixed beans and serve as a thick sausage and bean stew.
If I'm really pushed for time I have been know to cook a pack of microwave rice, then fry it up with frozen peas, onions, 5 spice, and eggs - egg fried rice in literally minutes, which costs about 50p a head. But I doubt it counts as a proper homemade meal
