I have also been trying to make meals ahead of time and freeze. I mostly use these for a quick/inexpensive lunch at work. There is a man who has a great blog and you tube videos called white-trash-cooking.com. Look for his link of his make ahead dinners and organized freezer, it will give you inspiration. I freeze alot of soups, stews, chili, and mashed potatoes, I will also roast a chicken, turkey, or pot roast and make gravy from the drippings. I can freeze the meat in individual servings and they also make great soups. Then I freeze the gravy in ice cube trays so I can just pull out one serving of gravy. I will spend an afternoon baking and make gallon size bags of different kinds of muffins, corn bread, and rolls. I can grab one for the road. They are great for nights when everyone wants something different or the nights when the family is on different schedules and making their own quick meals.
Individual mac and cheese, lasgna, manicotti and pot pies freeze well also.
Our grocery store also sells individual fish fillets. Very easy and quick to unthaw and broil as well.
