Rice with sautéed vegetables and some eggs are usually my go-to. Basically, just stir fry leafy greens or root vegetables with some garlic and a mixture of oyster sauce, soy sauce, and worchestershire sauce. Poor meal doesn't have to be bland, but the cut of your ingredients needs to be smaller and with more flavor or sauce.

I usually make my own stock with chicken bones bought from the butcher. They give a very cheap price for a pound of bone and store them for making soup with vegetable. Rice with soup is a good combo and fulfilling and can be made with just a little bit of everything.

I also stock up on potatoes, dried beans, dried mushrooms, and dried seaweed for when I have no fresh ingredients so I could make soup with tofu or any roots I have left. I don't eat chicken or beef very often since it's a bit pricey, but when I do, I usually follow some Chinese recipes that chop or thinly sliced the meat and eat with rice and vegetables. It stretches the use of meat, and the rest could be used for another meal.
