Preheat the oven to 350°F. Wash and dry each bell pepper, then cut them in half horizontally. Remove the stem from the top half carefully. Place halves in a 9x13-inch casserole dish, brush with 1 tablespoon of oil, and season with 1/4 teaspoon of salt and pepper. Bake for 20 minutes to soften, then set aside.
