Chicken stir-fry--chicken breast, veggies (such as broccoli, carrots, peppers, cauliflower etc.), and soy sauce/garlic/ginger. Cook up some brown rice to put it over. Speaking of rice, it freezes well--make a bunch and then put some in Gladware or other freezer container and stick it in the freezer. The turkey chili idea someone posted earlier is also good; with this or soups etc. I always make a large batch and freeze single servings for nights when I'm busy or just too tired to cook.
