Brown the Beef: In a large pot or Dutch oven, heat over medium-high heat. Brown the ground beef until no longer pink, breaking it up with a spoon. Drain any excess fat if desired.
Cook the Liver: Add the chopped or ground liver to the pot with the browned beef. Stir well and cook for an additional 5-7 minutes, or until the liver is cooked through. Be careful not to overcook the liver, as it can become tough.
Add Broth and Seasonings: Pour in the beef bone broth, scraping up any browned bits from the bottom of the pot. Add salt and pepper (if using) and stir to combine.
Simmer: Bring the mixture to a boil, then reduce heat to low and simmer uncovered for 20-30 minutes, allowing the flavors to meld and the broth to thicken slightly.
Season and Serve: If desired, adjust the seasoning with additional salt or pepper. Remove from heat and serve hot.
