Simple and easy; key word is EASY!! The steak/potato lunch thread got me wanting some warm spuds, as it never got above 60 degrees today.
Grease your pan so the bottom layer won’t stick and burn. Sliced potatoes, ring sausage, cream of mushroom soup, and a little cheddar love. Plenty of black pepper. Repeat for the second layer.
Cover and cook for about 60-80 minutes at 350 degrees (depending on your oven, and how thick you slice the potatoes). Then uncover - add a little more cheese on top, and back in for another 10-15 to melt and brown.
