Finely Dice the yellow onion and mix with italian saisage. There are two way to cook the Italian sausage in a pan or in the oven, I like to cook it in the oven pressed think into a pan at 365 for approx. 30 min or until cooked.

While meat is cooking dice peppers and put into a saucepan with a tablespoon of olive oil. Saute for 2 minutes just to sweeten lightly.

Drain the can of diced tomatoes and add to the peppers. Bring heat to medium to reduce slightly. About 5 minutes

Add jar of pasta sauce and simmer

Cook pasta Al dente, drain and run under cold water to stop them from over cooking, the pasta will finish in the oven with the sauce.

Add the sauce and meat to the pasta and mix well.

Put into oven at 350 for 30 minutes or until cheese is nice and melty. I like to put the broiler on high for a couple of minutes to put a nice golden brown on the cheese. Remove from oven and sprinkle with parsley.
