In a large skillet heat the olive oil. When almost smoking, add the onion and garlic and saute over medium heat until the onions become very soft, about 8 minutes.

Add the celery and carrot and saute for 5 minutes.

Raise heat to high and add the ground beef. Saute, stirring frequently and breaking up any large lumps and cook until meat is no longer pink, about 10 minutes.

Add the tomatoes, parsley and basil and cook over medium low heat until the sauce thickens, about a half hour.

Season with salt and pepper.

Finish bolognese with Pecorino Romano.

Meanwhile, bring a large pot of water to a boil over high heat.

Cook/boil pasta in a large pot according to package instructions until al dente.

Add the pasta directly from the pasta water to the sauce. Serve drizzled with more olive oil and sprinkled with more cheese if desired.
