For an extra layer of flavor, consider browning the shredded chicken in the skillet before adding it to the cauliflower rice mixture. Feel free to experiment with different types of cheese. Gruyere or Parmesan would be excellent additions. If you prefer a spicier dish, increase the amount of cayenne pepper or add a dash of hot sauce to the chicken mixture. To prevent the peppers from becoming soggy, you can par-bake them for 10 minutes before stuffing.
