I've been trying to come up with new ways to use up some of the older pantry items that we stocked up on at the beginning of the pandemic. This yummy casserole started with a recipe on the side of a box of instant mashed potatoes. I tweaked the recipe just a bit, and now even my "instant potato hating" husband likes it!
