Wash russet potatoes and slice them thinly. Place in a saucepan with cold water. Boil the potatoes for about 5 minutes. Drain the water and pat the potatoes dry. Spread them out on a greased baking sheet. Spray the potatoes with cooking spray. Top with a little salt and pepper. (I made a pan of just plain potatoes too.)
Then spread cheese and cooked, chopped bacon on top of that.
Bake at 375 degrees for 14-15 minutes.
