Made this one up and it was delicious. Hopefully I remember how I made it.
1 box manicotti noodles
15 oz ricotta cheese
2 c mozzarella cheese, shredded
1/2 c triple cheddar cheese, shredded
2 T dry parmesan cheese (you know the stuff)
2-3 baby portobello mushrooms, diced
1-11/2 c pasta sauce
2 Italian sausages
Boil noodles according to package, drain and set aside. In a bowl, mix cheeses (save 1 c of mozzarella for later), spices and mushrooms. Load into a piping sleeve. Get out a 9x13 pan, grease and spread a tiny bit of the pasta sauce in it. Pipe the cheese mixture into the noodles and line the pan. Take the sausage out of the lining and cook. Crumble as you cook it. Add to sauce and spread over the noodles. Bake, covered, at 350 for 30 mins. Then uncover and sprinkle remaining cheese on top. Bake uncovered for 10-15 minutes, until cheese gets golden and bubbly. Serve.
