Notes

  • Sauté the onions and bell peppers before mixing for an extra depth of flavor.
  • A great shortcut that adds extra seasoning and saves prep time.
  • Add sliced jalapeños or a pinch of cayenne for more heat.
  • If using brown rice, increase the baking time and add more broth to ensure proper cooking.
