1. Preheat oven to 400 degrees. Cook pasta according to package instructions. Drain; set aside.

2. Meanwhile, in a large saucepan, heat oil over medium. Add garlic; cook until fragrant, about 1 minute. Add tomatoes, oregano, and sugar. Bring to a boil, reduce to a simmer; cook, stirring and breaking up tomatoes until slightly thickened, 5 to 8 minutes. Season with salt.

3. Add pasta, sausage, and half the mozzarella; toss to combine. Transfer to a 2-quart baking dish. Top with remaining mozzarella and Parmesan. Bake until bubbly and top is lightly browned, 10 to 15 minutes. Serve with Romaine Salad.
