Add diced tomatoes, red wine and beef broth, remaining ghee and let sauce simmer about 10 minutes to thicken slightly.
Pour entire sauce mixture into a blender or food processor and puree until smooth or to the texture of your liking. Use for meatballs, spaghetti squash or anything else you can think of.
