I like using leftover chicken, shredding it, reheating it in butter in a small pan, then sprinkling some Mexican spices over it, olives and some Mexican cheese. Can do the same with any meat. Serve a little avocado on the side.
I also make my own bulk sausage with ground meat and a variety of seasonings. I make it into patties and freeze them, then thaw the night before I want to cook them and cook them in a pan. They're nice with some sautéed shredded zucchini or sautéed chopped cauliflower hash on the side.
