3-4 small boneless skinless chicken breasts (about 1 1/2 lbs/750g) or 2 large chicken breasts, split lengthwise
2 bell peppers 1 red and 1 green, seeded and cut into strips
1 medium onion minced
1 teaspoon ground cumin
1 1/2 teaspoon chilli powder
1 teaspoon garlic powder or minced garlic
2 teaspoons of paprika
Salt and freshly ground black pepper to taste
1 tablespoon vegetable oil
1 cup grated mozzarella cheese or your favorite cheese
Chopped fresh cilantro or parsley for garnish
Preheat your oven to 400°F (200°C) and lightly grease a baking dish.
Season chicken breasts on both sides with cumin, chili powder, garlic, paprika, salt and pepper.
Save some spices for later.
Place the chicken breasts in the prepared baking dish and drizzle with oil. Top with peppers and onions and sprinkle with remaining fajita seasonings. Finish with grated mozzarella cheese.

Serve immediately over cauliflower rice, steamed vegetables, zucchini noodles or on its own.
