Ravioli Bake

1 jar (26 oz.) spaghetti sauce
1 can (14 1/2 oz.) diced tomatoes, undrained
1/2 C. water
2 pkg. (1 lb. each) frozen ravioli in the flavor of your choice, thawed
1 pkg. (8 oz.) shredded mozzarella cheese
2 T. parmesan cheese

Heat oven to 400 degrees.  Mix spaghetti sauce, tomatoes, and water together.  Spoon 1 cup onto bottom of a 9x13-inch baking dish.  Layer half the ravioli and 1 cup cheese over sauce.  Top with remaining ravioli and sauce mixture.  Sprinkle with remaining cheese.  Cover and bake 30 minutes.  Uncover and bake 15 minutes or until ravioli is tender and heated through.  Sprinkle with parmesan cheese.  Let stand 10 minues before serving.

Tips & Tricks:
-I cut this recipe in half and used an 8-inch square baking dish.
-Feel free to substitute fresh chopped tomatoes for the canned ones.  You might want to add a little extra water though.
-It might be fun to use two different flavors of ravioli - like half beef filling and half cheese filling.
