Put all the ingredients for the meatballs in a food processor and blend until everything is mixed and minced. Transfer to a bowl.
Put a little oil in your hands, just enough to lightly coat fingers and palms and use a tablespoon to scoop up the beef mixture so the meatballs are the same size. Repeat process until all the beef mixture is used.
In a deep pan over medium high heat, add oil and the meatballs. Cover and cook for 5 minutes. Turn the meatballs over, cover and cook for another 5 or until meatballs are golden brown.
Mix all the ingredients for the dipping sauce in a bowl and serve together with beef meatballs. Pour over or use as a dipping sauce.
Serve with rice, tomatoes and a few cilantro leaves.
