Cheap things to make..hmm....
Get some staples.
Lettuce/whatever greens are on sale
You can make a lot with carrots and onions and potatoes.
One thing I like to make is fajitas, just marinate some chicken or beef cut into strips overnight in vinegar, pinch oregano, 1t sugar, chopped garlic, a little worcestershire sauce. In a separate bowl, marinate wedged onions, potatos, green peppers in the same stuff. Matchstick carrots too, I bet they would be goood.
Then heat a little oil in the wok, throw in the meat, when it's done remove it. Then fry the other stuff, when it seems done add the meat back in. Heat til hot and serve in tortillas. The potatoes thin it out so you don't have to use as much meat.
What kinds of food do you like? I mostly make asian stuff, like pad thai, mu shoo chicken, spicy thai stir-fry, etc. Many of these can be made really cheap if you get the produce in season, and meat on sale. Some of the sauces can be an investment but they last a while. Plus it's a tasty way to get your veggies in.
What kind of things do you like? Tell me and I will try and get up some easy recipes. I am not much of a cook either, I can't make a decent cake at ALL, but stir-fry type stuff is EASY. Just put in a bit of oil, add ingredients, stir till it looks and smells done.
