BAKED ZITI

1 pound ground beef round or extra-lean ground beef
1 cup chopped, peeled onion
8 cups chopped fresh tomatoes (about 3 pounds)
1 teaspoon dried basil leaves
1 1/2 teaspoons salt 
1/4 teaspoon ground pepper
8 ounces ziti, cooked according to package
directions and drained
4 ounces part-skim mozzarella cheese, cut into 1/2-inch cubes
2 tablespoons grated Parmesan

    In a large, heavy saucepot or Dutch oven cook ground beef 
and onions 10 minutes over moderately high heat, stirring 
occasionally to bread up beef.  When meat is brown and onions 
are soft, drain and discard fat in pot; add tomatoes, basil, 
salt and pepper.  Cook 30 minutes, stirring occasionally, until 
sauce is thickened and flavors are blended.  (Sauce may be made 
1 to 2 days ahead and refrigerated.)  Heat oven to 350 degrees.  
Mix ziti and tomato sauce in a 2 1/2-quart baking dish; stir in 
mozzarella; sprinkle with Parmesan.  Cover and bake 15 minutes; 
uncover and bake 15 minutes longer, until hot.  Makes 2 quarts.
