In a large skillet with a tall lip, heat the olive oil over medium high heat. Add the onion, garlic and Italian seasoning. Saute for about 2 minutes or until the onion is soft
Now add the crushed tomatoes, salt, pepper and garlic powder. Reduce the heat to a simmer and let the sauce cook for about 10 minutes stirring occasionally.
Then add the Alfredo Sauce and stir it into the crushed tomatoes. Taste the sauce and add more Italian seasoning, salt, pepper and garlic powder if you'd like. Simmer the sauce for about 5 minutes stirring occasionally.
Add a ladle of pasta water to the pink marinara Alfredo sauce and stir it in. Add the pasta to the sauce and stir until the pasta is coated in the sauce.
