Microwave the cauliflower rice for 5 minutes and preheat oven to 400ºF.
Heat the olive oil in a skillet over medium-high heat. Add the onion and carrot to the skillet and cook until soft, about 5-6 minutes. Add the garlic and cook until fragrant, about another minute. Finally, add the balsamic vinegar and stir everything together.
Push the veggies to the side of the skillet. Add the chicken and brown both sides before mincing and fully cooking.
Once the chicken is cooked, stir everything together and add the diced tomatoes, parmesan, seasoning, and cauliflower rice. Stir together, remove from the heat, and set aside. Salt and pepper to taste before filling the peppers.
Cut the peppers in half through the stem and remove any seeds and membranes. Spoon the filling in and bake on half sheet pan for 25 minutes before adding the shredded cheese on top and baking an additional 10-15 minutes. Top with fresh basil or parsley and enjoy!
