Spaghetti and Mini Meatballs

In a medium saucepan, heat oil over medium heat. Add onion and garlic; cook until softened, about 3 minutes. Break up whole tomatoes with your hands, then add to pan along with crushed tomatoes. Bring to a boil; reduce to a simmer, and cook until thickened, about 20 minutes. Season with salt and pepper.

Meanwhile, in a large pot of boiling salted water, cook spaghetti until al dente, according to package instructions. Drain.

Transfer 3 cups tomato sauce to a large skillet; bring to a simmer. Add Mini Meatballs; cover, and simmer until cooked through, about 10 minutes.

Transfer sauce and meatballs to a large bowl. Add pasta, and toss to combine. Serve immediately, sprinkled with cheese if desired.
