Instructions

  1. Step 1: Preheat the oven to 325°F. Toss 2 sliced green bell peppers, 2 sliced red bell peppers, and 2 thinly sliced yellow onions with 3 tablespoons olive oil, 1 teaspoon dried oregano, 1 teaspoon salt, 1/2 teaspoon black pepper, and 3 minced garlic cloves in a large roasting pan.
