Cut the tops off the bell peppers and remove the seeds and membranes. Place them in a baking dish and set aside.
Cut the cauliflower into florets and pulse in a food processor until it resembles rice.
Heat one tablespoon of olive oil in a large skillet over medium heat. Add the diced chicken and cook until browned and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add another tablespoon of olive oil and sauté the onion, garlic, and mushrooms until softened.
Add the cauliflower rice to the skillet and cook for 5-7 minutes, until it becomes tender.
Season with dried oregano, salt, and pepper. Stir in the cooked chicken and half of the shredded mozzarella cheese.
Spoon the cauliflower rice mixture into the bell peppers, filling them to the top. Sprinkle the remaining mozzarella cheese on top of each pepper.
Cover the baking dish with foil and bake in the preheated oven for 25 minutes. Then remove the foil and bake for an additional 10 minutes, or until the peppers are tender and the cheese is melted and bubbly.
Remove from the oven and let the stuffed peppers cool for a few minutes before serving. Enjoy!
