My cookbooks have a distinct lack of good casserole recipes. I like making big honking casseroles to cut up and pack as lunches for Rick and I, but I'm getting really bored with my lasagna and chicken enchilada casserole (both kick butt, but we need some variety).

So, calling all cooks, gimme your best casserole recipe(s), perferably something that I can make in vast quanities and can "F/T"! =D
