Pasta a la Gricia

Cook 1 pound of rigatoni in a colander placed in lightly salted boiling water.  Saute 1 package of Italian sausage cut into 1 inch pieces until golden brown.  Add 2 cups of the pasta water to the sausage and reduce by half.  Add cooked pasta along with 1 package of baby spinach and 2 cups of grated pecorino romano cheese.  Season with salt and pepper ( and crushed red pepper if you like it spicy).  The pasta water will make a sauce, serve with crusty Italian bread and mangia, mangia!
