I'm the one who cooks, and I know what food/casserole swaps (see note at end of post) are planned, so I make the list and we go together.
Food/casserole swaps happen between my niece, her daughter and myself. When any one of us makes a oven\time-intensive dish (meatloaf, lasagna, roasted chicken, or any type of casserole or soup) we make three and package two for the freezer. Once or twice a week, we get together and swap. Yesterday I went with two batches of turkey asparagus bake and two batches of Santa Fe Chicken. I came home with an eggplant lasagna, a batch of homemade French onion soup, a low-fat King Ranch casserole, and a half-dozen low-fat bean burritos -- all ready for the freezer.
