I don't know what kind of chicken can be cooked through in 3-5 minutes per side . . . doubled the cooking time. The tomato sauce was a bit watery as well. This is what I would do next time: Brown chicken on both sides. Remove from pan, add sauce to pan. Return chicken to pan and braise for 25 minutes. Remove chicken, add in other ingredients, serve. This would combat the watery sauce and the undercooked chicken.
