I am always looking for things I can make ahead and freeze. Because there are just two of us, I cook recipes designed for 9 by 12 casserole dishes in two 8 inch square pans. I eat one and have enough for left overs. Then can either share the spare or wrap it for freezing after I've cut it in half.
A great resource is ONCE A MONTH COOKING by Mim Wilson and Mary Beth Lagerborg. The recipes are kid friendly and bunches of food can be fixed ahead of time.
