I also go to the supermarket salad bar for salads that I'll eat at home. I very rarely go to a restaurant locally, though there are some very good choices in this town. I eat only one "real" meal per day, the rest being reserved for snacks - sometimes fruit, sometimes things far worse for me, LOL.
Every day I'll either have a salad (with healthy dressing that I have to buy hundreds of miles away) or, most often, steamed vegetables which almost always includes spinach among the others.
Unlike beacjguyj, I "cook for leftovers" - many of the things I cook, I hope to make at least two meals out of. A few times a year I'll cook a turkey, and I'll have a "meat ingredient" that I can use on a bunch of new meals later on.
I do some breakfast type things such as cooking eggs or pancakes...I don't do the hash browns/home fries (I can't make them come out very well) and it just happens that I don't use breakfast meats (sausage, bacon).
I'll often do some of the Asian meals that come in a box, such as some of the Thai dishes, various Indian dishes (very much enjoy Madras Lentils), etc. Though these are usually the size of a meal, I often end up with two meals once I've finished adding bean sprouts, mushrooms, meat (often leftover or frozen turkey or pork), etc.
Turkey as mentioned above, pork roasts, beef roasts, baked chicken. I still have that frozen mutton to try, haha. Any one of these provides meat as an ingredient for a number of later meals.
Meat-in-gravy over toast or smashed potatoes...
Noodle soup with vegetables and leftover meat added...
Four things that I really like, but haven't fixed in ages:
chili
"monggo" (diced pork, mung beans, onions, etc., over rice)
pepper steak over rice
Swiss steak
I've probably covered 80-85% of it
