For a spicier kick, add a pinch of red pepper flakes to the sirloin mixture while sautéing. Feel free to experiment with different types of cheese. Mozzarella or Monterey Jack would also be delicious. If you don't have an Instant Pot®, you can bake these in a preheated oven at 375°F (190°C) for about 30-40 minutes, or until the peppers are tender.
