In a large oven-safe skillet, heat your oil over medium heat.
Sauté the diced pepper and onion until soft, about 3 minutes.
Stir in your riced cauliflower, crushed tomatoes, bone broth and seasonings.
Allow the liquid to simmer, while stirring through the bottom of the pan.
Simmer for 5-6 minutes, until the cauliflower begins to get tender and the sauce thickens a bit.
Meanwhile, preheat your oven to 375 degrees f.
Add in your shredded chicken and stir to combine.
Sprinkle the top with cheese if desired and transfer the whole skillet to the oven. Bake for 15-18 minutes, or until the cheese is bubbly and golden on top.
Serve with toppings of choice.
Enjoy!
