Go-to casserole

Every cook needs an arsenal of ready-in-30-minutes recipes made from ingredients she always has on hand.

I cannot count the number of times I have made Chicken Enchilada Casserole in the last year.  Up until recently, I made half a recipe in an 8x8.  Now I sometimes make the full recipe in a 9x13.  Little Miss and I could eat half a pan. :)   

I make it easier (& always in my pantry) by using canned chicken from Sam's.

What recipes are in your arsenal? I'd love to add more (& more variety) to mine!
