Browning the Meats: In a large pot, brown the mixed meats over medium-high heat. If using bacon, allow it to render its fat, which will add flavor to the soup. Cook until all the meat is thoroughly browned.
Adding Broth: Pour the beef or chicken broth over the cooked meats. Stir well to combine, ensuring any browned bits on the bottom of the pot are incorporated into the broth for extra flavor.
Seasoning: Season the soup with salt, and if using, add black pepper. Adjust the seasoning to your taste preferences.
Simmering: Bring the soup to a simmer, then reduce the heat to low. Let it cook uncovered for 20-30 minutes, allowing the flavors to meld together and the broth to reduce slightly, concentrating the flavors.
Serving: Once the soup has thickened to your liking and the meats are tender, ladle the "minestrone" into bowls. Serve hot, offering a carnivore-friendly version of the classic hearty soup.
