Here is a quick go-to meal idea* that can be made cheap and fast. It's what I turn to when I'm lacking in creativity, money or time. However, it is really delicious. I've seen similar pocket sandwiches sold in the supermarket for a lot more. Start out by sauteeing veggies in a small pan. Whatever veggies you like. I usually use zucchini, onions, sliced garlic cloves, various squash, sometimes carrot, bell pepper strips etc. While those are cooking open a whole grain pita pocket and spread a bit of spaghetti sauce on the inside. Microwave for a few seconds, maybe 20 just to warm it up. When veggies are soft pile them into the pita and enjoy!
