Most of mine have been mentioned, but here's my list:
Turkey or chicken soup - just add dumplings after thawing
Lentil Soup
Squash Soup
Lasagna
Eggplant Parmesan
Beef Stew
Hobo Stew
Chicken Chili
Beef Stroganoff - thaw and serve on top of egg noodles
Taco Meat - usually leftover beef from pot roast that's shredded and seasoned
Tomato Sauce and Meatballs
Chicken, Artichoke, Rice Casserole
Shredded Pork w/ barbecue sauce (leftovers from Cranberry Pork Roast)
Chili Colorado (this is a time intesive yet easy recipe, so I double it and freeze half. It's really not chili though - it's served in a tortilla)
I also try to have shredded, cooked chicken or turkey in the freezer at all times. It makes other recipes much easier to prep at dinnertime.
