Stuffed Shells with Spicy Sausage and Ricotta

One of my favorite types of pasta is anything involving ricotta- manicotti, lasagna, ravioli, stuffed shells, unmatched to most pasta dishes for me. This recipe for stuffed shells with sausage and ricotta is so simple and freezes amazingly, broken into 2 pans, feeding 4 adults per pan, OR feeding 8 for one large pan.
