Heat a large pot or Dutch oven over medium-high heat. Add the ground beef, onion, and garlic, breaking up the meat with a spoon. Cook until browned, drain excess fat if needed.

Add the canned whole tomatoes with the liquid, tomato sauce, green bell pepper, water, Italian seasoning, bay leaves, and sugar to the pot. Stir well to combine.

Bring the mixture to a boil. Reduce the heat and simmer uncovered for 1 hour or until the sauce has reached your desired consistency. Stir occasionally.

Remove bay leaves, taste and season with additional salt and pepper. Serve over hot pasta.
