Add oil to a skillet over high heat. Remove the rind from 3 slices of Brie. Whisk eggs for 1 minute. While moving the skillet in a circular motion, pour the eggs in continuing motion, cook until the outside edges are firm (approximately 1 minute). Then flip the omelet to finish cooking (about 30 seconds). Place the cheese slices in the center and fold the omelet. Salt and pepper to taste.
