Oven at 400 degrees. Slice your washed, un-peeled potatoes, about four large ones depending on your pan. I use an old cookie sheet that I no longer use for cookies, and drizzle it generously with oil. Place the slices of potato in a single layer, drizzle for olive oil, generous salt and pepper. Let them cook about 4o or so minutes. Flip them over half-way through.
I served these with a dip that had yogurt, mayo, and horseradish. They were gone in minutes!
