I had this dish on a trip to Sicily in 2006. It has become one of our favorites. It is unbelievably good. Each time I have it, I am transported to the lovely trattoria in Taormina where I had this for lunch.
Heat the olive oil in a large skillet. Add the chopped onion and garlic and saute until translucent. Stir in the crushed tomatoes and basil. Cook until the sauce thickens, about 20 minutes, stirring occasionally.
In the meantime, beat the butter and gorgonzola cheese by hand until well blended together.
Boil your pasta according to the directions. When just about tender, drain well and return to the pot. Add the gorgonzola, butter mixture to your tomato sauce. Add the drained pasta to the sauce and stir to coat. Season with salt and pepper to taste. Top with the grated cheese and enjoy!!!! MANGIA BENE.
