Cannelloni with Cheese Sauce

2 cups marinara sauce
1/4 lb ground beef, browned
1/4 lb italian sausage, browned
1 cup onion, chopped and sauteed
6 cannelloni, large
1 cup white sauce
6 oz cheddar cheese, grated
2 T parmesan cheese, freshly grated

To make filling, combine browned beef, browned sausage, sauteed onion and marinara sauce. Cook cannelloni as directed, but cook for only 3/4 of the recommended time; rinse and drain. Fill cannelloni with filling mixture and pack firmly into greased baking dish.

To make cheese sauce, warm white sauce until nearly boiling; add grated cheddar cheese and stir until melted. Pour over cannelloni, coating pasta generously. Cool.

To freeze, cover baking dish with foil; place in freezer bag and freeze.

To prepare, uncover and bake frozen casserole in 400d oven for 1 hour, or until hot and bubbling. Sprinkle with the Parmesan cheese, return to oven for 5 minutes to brown top.
