In a large saucepan set over medium-high heat, brown the salt pork, ham, bacon, chopped carrot, and chopped onions. Add the tomatoes to the pan, reduce the heat to medium, and cook them down for 5 minutes. Add the bay leaf and chopped garlic to the pan. Season the sauce with the salt and pepper, to taste, reduce the heat slightly, and continue simmering the mixture for 15 minutes.
