Heat oil over medium high heat.

Add chicken to pan and brown on both sides, turning once.

Stir in Ragu sauce and reduce heat to a simmer (low or medium low).

Cover and allow to cook for 15 to 30 minutes. (Larger pieces of chicken will take more time. Cook until internal temperature reaches 165°.)

Remove cover and stir in mozzarella.

Continue heating until mozzarella is melted, stirring and spooning sauce over the chicken.

Serve with veggies or pasta.

Enjoy!
