116 oz. box ziti pasta, cooked al dente (The pasta should be firm, not hard. The pasta will cook a bit more when you bake it, so my rule of thumb is about 2 minutes less than the directions call for.
2cupsmozzarella, grated or 4-5 mozzarella cheese sticks cut into 8 pieces each
Saute the onion, bell pepper and salt for 4-5 minutes or until onions are translucent. Add the garlic and cook an additional minute.
Add the tomatoes and cook the sauce for 15 minutes over medium heat. The sauce will thicken as it cooks.
Preheat oven to 350 degrees.
Combine the sauce, pasta, parmesan and 1 1/2 cups mozzarella in a large bowl or pot and pour into a lightly oiled 9 x 11 casserole dish. Top with remaining 1/2 cup mozzarella. Can be prepared at this point the night before.
Bake uncovered for 30 minutes or until golden and bubbly.
