Topped with homemade tomato sauce and meatballs, Spaghetti with Meatballs is a traditional pasta dish that doesn't disappoint.
Pre-heat oven to 350°F.
In a large saucepan, heat oil over medium-high heat, and add the onion and green pepper. Cook until the onion is translucent (about 5-10 minutes).
Add garlic and cook for 1 more minute.
Stir in diced tomatoes, tomato sauce, and tomato paste into the pan. Season with oregano, basil, salt, and pepper. Simmer spaghetti sauce for 20 minutes to 1 hour, stirring occasionally.
