Combine all chimichurri ingredients except olive oil in a blender or food processor and process until finely chopped. Transfer to a bowl and stir in the olive oil (blending it will make it bitter). Season to taste with more salt and pepper, if desired. (This will keep for 2 days in the refrigerator.)
Combine all meatball ingredients in a large bowl and use your hands to mix until evenly combined. Form into about 1 tablespoon size meatballs, about 20 meatballs.
Heat a large pot over medium-high heat. When hot, add the avocado oil. When the oil is hot, add the meatballs. Cook until golden, turning occasionally until browned on all sides, about 10-15 minutes. Remove to a large plate and toss with half the chimichurri, serve with remaining sauce drizzled over top.
Notes
You can also bake the meatballs in a 350ºF preheated oven. Simply line a rimmed baking sheet with foil and/or baking parchment, place ~2 tablespoon size meatballs on top, and bake for 15-20 minutes, or until cooked through. I like to broil them for about 4-5 minutes just to brown them before serving.Protein:Energy Quotient [calories]: 1.02
