Heat 1 tablespoon olive oil over medium heat in a large skillet. Add red pepper flake when hot and sauté for about one minute. Add in onions and cook until they are translucent. When the onions are almost done, add in garlic and cook for a minute or two.
Add an additional tablespoon of oil if needed, and add Italian Chicken Sausage chunks. Add in oregano and basil and cook the sausage for 3-4 minutes, or until it starts to brown.
Stir in alfredo and marinara sauce and cook over medium heat for a few minutes. Reduce the heat to low and simmer for 15 - 20 minutes over low heat.
Add in cooked pasta and stir to combine.
Garnish with fresh grated parmesan cheese and chopped fresh parsley.
