This spaghetti recipe is light on the sauce, which is more typical of how spaghetti is actually served in Italy. If you would like more sauce, you may want to thin it with water or add more canned tomatoes to the sauce. Make the sauce and boil the spaghetti simultaneously. The sauce should be done in the time it takes to heat the pasta water and cook the spaghetti. Feel free to vary the amount of sausage for the sauce. We use anywhere from 1/2 pound to a full pound of Italian sausage, half sweet, half spicy.
