Some markets sell roasted red bell peppers in jars.
Or, to roast bell peppers, line a baking sheet or jelly-roll pan with aluminum foil, using enough foil so that you have extra on the sides. Place peppers in a single layer on top of foil. Broil 6-8 inches below broiler element. Rotate to char on all sides. Remove from oven and draw up sides of foil to enclose peppers.
