In you pan, add the beef, break apart and cook. Halfway through add the onion. Once cooked add the garlic and cook for 1 min. Next add the flour, salt, and Worcestershire. Stir until combined. Add the chicken stock and deglaze the pan (if needed). Add the Italian seasoning, red pepper flakes and pasta sauce. Bring to a boil and then reduce to a simmer and cook for 15 mins. In the meantime boil your noodles. Once done, add the half and half and cheese and mix. Toss in the cheese and eat!
Enjoy!
