My go-to cheap (pretty much the price of a pack of ramen!) and quick meal, that feels like real food, is aromatic peas with couscous.
Get a frying pan with a little oil, add a spoon full of garlic paste/smooshed garlic, a teaspoon of cumin and a teaspoon of turmeric, some salt and a lot of black pepper, fry that up for a minute. Then add a chopped onion, fry until soft. Then add frozen peas. Mix it all up and leave it to cook, stirring occasionally. In the meantime, put some couscous in a bowl, about a cup, add hot water to cover the couscous, with about half an inch extra water on top, then cover with a plate. Leave that for about 5 minutes, in the meantime finish the peas off with some more pepper. When you're ready, fluff up the couscous with a fork, mix everything - done! If you have too many peas, shove them in a box of some form and you have your own microwave couscous mix ready to be deployed at any time.
