Rinse the sweet peppers and pat dry

Carefully place 5-6 peppers on a skewer, pressing each pepper firmly against the other (this makes them easier to flip when grilling)

Continue adding peppers to next skewer, making 4 skewers total

Lightly coat peppers with oil

Place skewered peppers on hot grill and let cook 5 to 7 minutes

Using grill tongs or spatula, carefully flip each skewer

Let cook a an additional 5 to 7 minutes and remove skewers from gril

Serve immediately or keep warm in heated oven
