Preheat oven to 425°F and lightly grease a baking sheet with cooking spray.
Wash and dry jalapenos, then cut in half, remove stems, and de-seed. Place on baking sheet with inside of pepper facing up spaced about 1 inch apart. Lightly spray with cooking oil and salt and pepper to taste. Flip over and lightly spray with cooking oil.
Bake for 16-19 minutes, until edges of jalapeno start to brown and skin starts to separate. Put in an air proof container (I prefer glass due to high temperature) and cover for 10-15 minutes if peeling off skins. This will help loosen the skins so they come off easily.
Once cooled, store in covered in the refrigerator. Enjoy!
