Taco bake freezes really well too! I have a few in my freezer right now for busy nights.
Spicy beef casserole with mock cornbread is a family favorite.
Crack slaw is one of my favorite things to do with leftover meat. It doesn't freeze well, though. You could cook and cut up the meat and freeze that, because the meal comes together in 10 minutes.
