Work the meat with your hands until everything is evenly mixed.

Divide the meat mixture into 16 equal portions, shaping each into a patty..

Heat a large skillet over medium-high heat. Add olive oil to prime the skillet.

Brown the patties well on one side, about 5 minutes, before flipping. Continue cooking until cooked through. Remove patties to paper toweling and keep warm. Cook in batches until all the patties are done.

Carefully use a spoon to remove all but about 2 tablespoons of grease from the skillet. 

Add the mushrooms and the beef broth to the skillet, scrape the bottom of the pan to remove any cooked on pieces.

Bring to a simmer and cook until the mushrooms are softened.

Stir in sour cream.
