Easy Parmesan chicken

This is a crockpot dish we tried earlier this week and just loved.  My kids asked for seconds which is always a sign that they will have it again.

1 medium onion, cut into thin wedges

1 TBSP olive oil
4 boneless, skinless chicken breasts
1 jar of spaghetti sauce
1/2 tsp dried basil
1/2 tsp dried oregano
1 bay leaf
1/2 cup shredded mozzarella
1/4 grated parmesan cheese
Cooked pasta
Place onion in crockpot.

Heat oil in skillet over medium high heat until hot. Lightly brown chicken on both sides. Place Chicken in crockpot. Pour pasta sauce over chicken, add basil, oregano and bay leaf. Cook on Low for 6-7 hours or on high 3-4, or until chicken is tender (I did it for 6 and the chicken just fell apart) Remove lid and discard bay leaf.
Sprinkle chicken with cheeses. Cook, uncovered on low for 15-30 minutes or until cheesse have melted. Serve over spaghetti.
