My go to meal isn't all THAT healthy (could be healthier):
You brown some hamburger and throw it in a roaster with cream of mushroom soup, and whatever vegetables you can find (broccoli, cauliflower, carrots, mushrooms, peppers, brussel sprouts are my fav in this, onions, potatoes; no tomatoes or cabbage or cucumbers of course), bake until vegetables are cooked. You can also add egg noodles and grated cheese.
I almost always have the ingredients for this in the house.
I'm not a huge meat eater, though I usually have meat in the freezer. My mom gave it to me; organic beef and pork. I don't use it much so when things get desperate (like this week with next to no money in the bank), I start pulling out the meat and have it with rice. Since I mostly only ever eat at work, I can get away with just taking some meat to work with some fruit cups, a fruit, and a pudding.. I don't have to make an entire meal if I don't want to or if I can't.
