Set the broiler to high. Line a baking sheet with aluminum foil.

Place the peppers on the foil lined sheet, and spray with cooking spray.

Broil for 6 minutes. Flip the peppers, spray again, and broil for another 6 minutes.

Remove the peppers from the heat, and ( carefully! ) wrap them together in the foil that lined the pan, making a little steam packet. Leave the peppers to steam for at least 10 minutes.

Open the packet, spray your fingers and hands with cooking spray to protect them from the hot oils of the peppers, and remove the skin from the peppers. Also, remove the stem and the seeds. Discard the skin, stem, and seeds.

Your peppers are now ready to be used in any dish you'd like.
