Preheat the oven broiler on high. Arrange the poblano peppers on a baking sheet and broil them on the top rack for 3 to 5 minutes per side, or until the skin is bubbly and slightly charred. Remove the baking sheet from the oven and cover with aluminum foil, allowing the peppers to sweat for 5 minutes. Afterwards, peel the skin off the peppers, remove their seeds, and slice them into thin strips.
