pasta casseroles would go a long way and are easy do it ahead dishes. I don't mean lasagna because that can be expensive. But, meat, rotini, sauce, cheese in large pans would go a long way. Then breads, salad, dessert. Keep it simple. You can make these types of casseroles and then freeze before the baking step. Making the day they arrive MUCH easier if the main dish is already prepared.
