Sausage, Spinach, Pasta

One of my favorite "one pot meals" ( Okay; it's a very limited category; I need to do more research ! ). Sweet Italian sausage, cut lengthwise and then into 1 inch pieces. After 2-3 minutes, add 1 large onion, chopped. Add 5-6 cups chicken broth; bring to a boil. Add 1 pound of pasta; broken into thirds ( if it's spaghetti or linguine, for example ). Cook and stir for about 8 minutes, then add 2 10 ounce packages of spinach ( fresh not frozen ! ). Wilt; then stir in 1/2 cup Parmesan cheese and 1 cup half-and-half. This seems better the day after; I put it in Tupperware and freeze it to bring it for lunch.
