In a 9x13 baking dish that has been sprayed with cooking oil, combine the following ingredients:
8 oz. ricotta
1 tsp. salt
2 c. ziti ( I sometimes use mini ziti)
1 jar of your favorite marinara sauce
(I use my own homemade sauce - 1 quart)
3 c. water
Stir all ingredients to combine and top with 2 c. mozarella cheese.
Cover with foil and bake at 350 for 40 minutes.
Remove foil and bake another 10 minutes.
Adjust your baking time according to how hot your over is.
The casserole is done when the liquid is absorbed.
Remember: if you want to add a little meat flavor,
add 1/4 lb. chopped proscuitto.
