I substituted Ricotta Cheese for the Cottage Cheese. I used Sweet Italian Sausage links. I removed the sausages from the casings and ground the sausage and the ground beef with the meat and cheese grinder attachment on my stand mixer using the coarse grinding plate. To try to meld the meat products together I alternated the sausage and the ground beef.
Next time I'll use the ready to bake lasagna noodles and I'll get commercially shredded mozzarella, the fresh mozzarella tasted very good, but cleaning up the food processor was not pleasant.
We've got dinner for two for 4 more nights. ;)
