Here's a side dish that goes with about anything, BBQ, chicken, steak, etc.........
Baked Potato Casserole
You can use fresh mashed potatoes, instant, or leftovers....I've also used hash-browns.
Fry up some bacon, let set, and than crumble to make bacon bits.
Spread potatoes in a casserole dish about 1/2 inch thick, and even.
Spread 2 tbs of melted butter over potatoes and sprinkle just a little salt and pepper
Spread a thin layer of sour cream on top of that.
Sprinkle bacon bits over that.
Add a thin layer of cheddar cheese (or your favorite, I use four cheese Mexican)
Do it all over again until you have two layers of everything.
Since everything is already cooked, heat in oven at 300-350 degrees until the cheese is melted.
