Remove peppers from the plastic and stem, seed and skin them. The skins should peel off easily after being steamed in the plastic. NOTE: If the skins are not coming off easily reheat the oven to 400*, place the peppers back in the oven (out of the plastic!) and turn off the oven. Let them slow roast another 30 min then rewrap in the plastic and let sit 30 more minutes. Some peppers have thicker skins than others.
