Cook the penne pasta as directed on package. (You can use GF pasta or regular pasta)
Cut the sausage into slices.
Cook the sausage in a skillet on medium-high heat, and continue cooking until browned on all sides and no longer pink in the center. Remove and set aside.
Using the grease from the sausages, saute the onion, bell peppers, garlic and spices. Stir frequently. Add oil if needed. Cook until the peppers and onion are softened.
Once the peppers and onions are soft, add a jar of marina sauce and the slices of sausage. Simmer for 5 minutes.
Pour the sausage and sauce mixture on the prepared penne pasta.
Sprinkle with seasonings as desired, parsley, red pepper flakes and Parmesan cheese.
