Preheat the oven to 350 degrees. Slice the potatoes 1/8 of an inch thick. Toss the potato slices with the olive oil. Lay the potato slices on a baking sheet. Bake for 10 minutes, or until the potato slices are crisp. Remove the potatoes from the oven and allow to cool. In a small bowl, combine the goat cheese and the sour cream. Season with salt and pepper. Using a pastry bag, pipe small rosettes of the goat cheese mixture onto the potato slices. Sprinkle with a few red pepper brunoise. Place some caviar on top of the goat cheese rosette.
