To make the meatballs, mix ground beef, almond flour, egg, Parmesan cheese, salt, onion powder, pepper and garlic. Form into meatballs. This made 24 meatballs for me.
Pour oil into a large skillet and brown the meatballs. When browned take out of pan and set aside.
Add mushrooms to the pan and brown. Once brown, add the Better than Bouillon mixed with water and deglaze pan.
Place the meatballs back in pan, cover and cook for 10 minutes.
When meatballs are cooked, take off the stove and mix in sou r cream.
Serve as is or over zucchini noodles.
