I’m going to be busy in the kitchen cooking up a storm preparing for the “Big Day”! I’m sure I’ll have prepared way too much food and the refrigerator will be stuffed with leftovers. When we’re tired of Turkey Sandwiches, and reheated Turkey dinner…I’ll whip up this delicious comforting Leftover Thanksgiving Casserole. The addition of White sauce and Swiss Cheese changes it up just enough to make all those leftovers new and exciting!
