Cook Rigatoni pasta according to package instruction. I like mine when the size doubles. About twenty minutes cooking.

Slice sausage into bit size pieces using scissors. Brown sausage in the large skillet. Drain excess oil if you want. I keep excess oil when I cook this.

Stir in onion and tomato paste. Stir constantly until onions is tender and sausage is cooked through.

Stir in the Italian dressing. Turn off heat and add in cooked Rigatoni pasta. Gently mix to coat pasta with the sauce. Sprinkle with parmesan cheese and lots of parsley.

Stir in sausage mixture into the cooked rigatoni and add in parsley and parmesan cheese.

Serve hot. Make lots for leftover and just heat it up in the microwave.
