Creamy Baked Ziti

We ate green salad with this dish and it was really good. I think next time I'll throw in some chicken chunks or browned hamburger.
__________________________

4 cups ziti pasta, uncooked (I used whole wheat Penne pasta instead)

1 jar (26 oz.) marinara sauce

1 can (14-1/2 oz.) diced tomatoes, undrained

6 oz. (3/4 of 8-oz. pkg.) Cream Cheese, cubed

3/4 cup Sour Cream

1 pkg. (8 oz.) Shredded Mozzarella Cheese 

1/3 cup Grated Parmesan Cheese

HEAT oven to 375ºF.

COOK pasta in large saucepan as directed on package, omitting salt. Remove from pan; drain. Meanwhile, add marinara sauce, tomatoes and cream cheese to same pan; cook on medium heat 5 min. or until cream cheese is melted and mixture is well blended, stirring frequently. Return pasta to pan; mix well.

LAYER half the pasta mixture in 13×9-inch baking dish; cover with layers of sour cream, 1 cup mozzarella and remaining pasta mixture. Top with remaining mozzarella and Parmesan.

BAKE 20 min. or until heated through.

Make Ahead: The pasta dish may be covered and refrigerated up to 8 hours before baking. Increase baking time to 30 to 35 min. or until heated through.
