Obviously defrost chicken

Preheat oven to 350°F

Place chicken into casserole dish

Season chicken on both sides with garlic powder, salt and pepper to your preference. I add a lot of garlic but that's just me.

Cook chicken till done in the center and drain any fluids accumulated if needed

Spread the entire jar or can of spaghetti sauce over all the chicken till completely covered

Place chicken back in oven for 10 mins to let the sauce cook into the chicken

Take chicken out and sprinkle shredded cheese over all the chicken. The more cheese the better

Place chicken back in oven for few mins to let cheese get all gooey and melted.

Take chicken put of oven and serve. We personally think that garlic mashed potatoes go amazingly with the chicken but whatever you fancy should go good as well
