I'm a poor guy too, so finding quality meats can be difficult. I actually feel protein is over rated. So alot of the animal products I eat is the actual fat. I order either beef tallow or lard in bulk, and cook veggies or rice/beans with them. There's a couple places i order them from online, i can tell you if you're interested. If you live near a farm sometimes you can get it there too. Just make sure you don't get it hydrogenated. For cheap sources of sustainable meat i get wild alaskan pollock or wild alaskan salmon in can... although i'd be careful with the canned stuff... i've heard that its not the healthiest thing in the world... But i keep a few in the pantry for convenience. The wild alaskan pollock I get perserved in salt. I believe they sell it at most grocery stores and it costs about four dollars for a 1 pound package. It will usually last me about a week. Good luck, I hope this helps.
