I had the same strategy when I was pregnant with my son last summer. You can cook up a large quantity of taco meat and package in smaller tupperware for quick tacos or taco salads. You could cook hamburger patties and freeze them in individual freezer bags for quick thawing and reheating. You could freeze sloppy joe meet for sandwiches later. Or how about meatloaf or meat balls or italian beef? You can also freeze things like banana bread, muffins & cookies for thawing later.
Here are a couple of other recipes for casserole type dishes that freeze well:
Green bean chicken casserole:

1 envelope onion soup mix
3/4 cup shredded cheddar cheese
2/3 cup french fried onions
Combine chicken, beans, soups, mushrooms, rice, onion, green pepper, onion soup mix. Spoon into greased 2 qt baking dish. Sprinkle with cheese. Cover and freeze. When ready to use - completely thaw casserole in refrigerator. Remove from fridge 30 minutes before baking. Cover and bake at 350 degrees for 60-65 minutes or until heated through.
