In a large pan or Dutch oven, cook the ground beef, ground pork, olive oil, onion, bell pepper, and garlic until the meat is cooked through and the vegetables have softened. Drain any excess grease, and return to the pan.
1 pound ground beef, 1 pound ground pork, ¼ cup olive oil, 1 yellow onion, 1 green bell pepper, 5 to 6 cloves garlic
Place the tomatoes in a food processor, and pulse 3 to 4 times until they are broken down into chunks but not pureed.
84 ounces whole San Marzano tomatoes
Add the pureed tomatoes, tomato paste, oregano, basil, thyme, salt, and bay leaf to the pan. Stir to combine.
6 ounces tomato paste, 3 teaspoons dried oregano, 1 teaspoon dried basil, 1 teaspoon dried thyme, 1 bay leaf, 1 teaspoon salt
Pour in the beef broth and red wine. Bring to a boil, then reduce to a simmer. Continue simmering, uncovered, for 2 hours or until the sauce has thickened to the desired consistency.
2 ½ cups beef broth, ½ cup dry red wine
Taste, add additional salt, and adjust seasonings if necessary. Discard the bay leaf, and serve over your favorite pasta.
