One Pot Pesto Alfredo Sausage Pasta

1. In a pot, brown the 4 sliced spinach feta chicken sausages. Remove the sausage and set aside.
2. Cook the package of rigatoni according to package directions in the same pot, reserving a couple splashes of pasta water before draining.
3. While the pasta is cooking, prepare the sauce. Add 1 container of pesto, 1/2 cup heavy whipping cream, 1/2 cup Parmesan cheese, and 1/2 tablespoon of red pepper flakes (if using) to the pot.
4. Add a couple splashes of the reserved pasta water to the sauce and simmer until it has thickened.
5. Return the browned sausage and the cooked rigatoni to the pot with the sauce. Mix everything together thoroughly.
6. Serve immediately, sprinkled with more Parmesan cheese.
