@lori0857: Heat a nonstick skillet over medium heat. Arrange pepperoni in the pan and sprinkle with ½ cup mozzarella. Place tortilla on top, press gently, and rotate slightly so the cheese sticks. Flip, sprinkle with red pepper flakes and oregano, then add remaining mozzarella to one half. Fold in half and cook 1–2 minutes per side until golden, crispy, and melted. Slice into wedges and serve warm with pizza sauce, ranch, or marinara.
