Mom's Chicken in Tomato Marsala Sauce

2 large skinless, boneless chicken breasts (Or I've used 8 breast tenderloins)
1/2 t. oregano
1/4 t. garlic powder
1/4 t. onion powder
1/4 t. black pepper
4 oz. fresh mushrooms, sliced
8 oz can tomato sauce
1/4 c. marsala wine

Combine oregano, garlic powder, onion powder, and pepper. Sprinkle generously over chicken. Heat frying pan over medium heat for 1 minute. Spray with cooking spray (remove from burner for this). Add chicken and cook 6 minutes. Push chicken to the side and add tomato sauce and wine. Stir in mushrooms and mix well. Arrange chicken in sauce and simmer about 12 minutes. Serve with linguine
