You should be ready to boil your pasta. Add the olive oil, cheeses and 2-4 Tbs. of black pepper (Your Discretion). Mash the life out of it until it becomes a paste. (Go back to the sausage and throw the cherry tomatoes in. Cook on low until liquid is gone). When your pasta is just about al dente, add in a ladle of pasta water. Mix. Add another ladle.
