Italian Sausage Supper

Here is what I am making for dinner.

1 pound mild Italian sausage, casing removed
1 cup chopped onion
3 medium zucchini, sliced (about 1 1/2 cups)
2/3 cup (6 oz can) tomato paste
1 cup water
1 tsp dried basil
1/2 tsp salt
3 cups cooked rice
1 cup shredded mozzarella cheese
1/4 cup grated Romano cheese

In a large skillet, brown sausage with onion, stirring to break up sausage; drain reserving 1 tbs drippings.

Spoon sausage mixture into a greased 2 qt casserole dish. Add zucchini to skillet; saute for 5 minutes until crisp tender.

In a medium bowl, combine tomato paste, water, basil and salt. Stir in rice. Spoon over sausage mixture. Arrange zucchini slices on top; sprinkle with the cheeses. Cover and bake at 350 for 20 minutes.
