I just threw this together and it turned out pretty good!
1 yellow onion, chopped
3 cloves of garlic, minced
1 lb boneless chicken breast, cut into small pieces
8 oz sliced mushrooms
1 jar/can tomato sauce (I used the four cheese)
1 lb pasta (I used linguine)
1 cup Parmesan cheese.
Put up a large pot of water to boil for the pasta. Salt the water when it boils and then add the pasta and cook according to the directions on the box. Saute the onion and garlic and then add the chicken. Cook until the chicken is brown and cooked through. Saute the mushrooms in another pan and then add them and the jar of sauce to the big saute pan. Let cook through and then add the pasta and mix in the cheese.
