Wow! Great ideas! Thanks everybody! I haven't been on the computer in a couple of days so just got all the responses at once. Today I've been out all day, have out of town company and a fussy baby. I wish I had those pre-made dinners already!
Hatvany, do you have a particular brand name that you use? I don't know that I've ever seen what you're talking about except for the styrofoam ones and I'm afraid they would melt and they didn't have lids.
Leigh, I want to do things like meatloaf and mashed potatoes, chicken and stuffing, fish sticks and fries, just anything that you would cook for a regular meal.
