Preheat oven to 425°. In a small bowl, combine ricotta, 1/2 teaspoon Italian seasoning, salt and pepper. Slice zucchini lengthwise into twelve 1/8-in.-thick slices. Top each slice with 1 rounded tablespoonful cheese mixture. Roll up and secure with toothpicks; place seam side down in an ungreased 8-in. baking dish.
Combine tomatoes, tomato sauce, tomato paste and remaining 1 teaspoon Italian seasoning; pour over rolls. Cover and bake until bubbly, 20-25 minutes. Remove toothpicks before serving. If desired, sprinkle with Parmesan cheese.
