2Heat a large skillet over medium-high heat. Brown patties in batches in the hot skillet until crispy on both sides and no longer pink in the center, about 10 minutes. Set meatballs aside in a rimmed serving dish.
3Reduce heat to medium and stir remaining chopped onion into drippings in the skillet. Season with salt and pepper. Cook, stirring constantly, until onion has softened and turned translucent, about 5 minutes. Stir in remaining garlic and cook for 30 seconds. Stir in Roma tomatoes, dried parsley, and ras el hanout. Pour in water. Cook until tomatoes are soft, about 5 minutes.
