Preheat oven to 400. Line a baking sheet with aluminum foil, brush it with 1 tablespoon olive oil, and brush the peppers with another tablespoon olive oil and place in oven. Set the timer for 8 minutes, turn the peppers, and roast another 8 minutes or until the skin is bubbly all over. Place peppers in a bowl, cover with the same aluminum foil from the baking sheet and let them cool.
