Skillet “Pizza” Chicken

Preheat an oven-proof skillet to medium-high heat. Add olive oil, then place chicken in, being careful not to overcrowd, and brown on each side for 3-5 minutes. Remove chicken from the skillet and place onto a large plate. Reduce heat slightly and add onion and garlic to the pan along with red pepper flakes and more salt and pepper; sauté for another couple of minutes. Add in anchovy paste and fresh tomatoes and cook until the tomatoes start to burst. Pour in canned tomatoes and season with more salt and pepper, then add chopped basil. Add chicken back into the sauce and bring to a simmer. Place a lid on the skillet and let cook for 15-20 minutes until the chicken has cooked through. Place the oven on broil and sprinkle mozzarella over the top of the chicken and sauce. Broil for 3-5 minutes until the cheese is melty and browned slightly. Sprinkle with more fresh basil and serve immediately.
