I love cooking as well, and I've been learning from my girlfriend.
We bought a 25 lb bag of pinto beans and every few days I boil a huge pot of them with jalapenos, habaneros, onions, garlic, and paprika. You can fry/mash them and make burritos, eat them alone, add them to brown rice, soup, etc. They're very healthy, yet inexpensive... rid me of digestive problems too!
We eat them with homemade salsa, which usually consists of onions, tomatoes, cilantro, garlic, and several of every pepper the market carries. This last time we used 5 different types of chili pepper and made almost a gallon of very spicy salsa.
Also pretty much any vegetables and meat diced and stir fried with teriyaki sauce is good.
It isn't hard to improvise if you know some basic rules... like lower heat and longer time means more thoroughly / evenly cooked. You just have to experiment and learn from various recipes, as was previously suggested.
If you ever plan to cook squid, we recently figured out the absolute perfect procedure for making it really tender. Usually squid ends up rubbery unless you get your timing just right.
You just have to boil a pot of water, then turn the heat off and drop the squid in, and let it cool down over a very long time. That seems to cook it just enough. Squid is really good in spaghetti, curry, or phở.
