Over medium heat, pour 2 tablespoons of olive oil into a pan. Add onions and caramelize. (You must have patience here, this is where the magic happens, do not let them burn!)
Once onions have the perfect color, add garlic, stir to incorporate, and cook for 30 seconds. Add spinach and meatballs, season with salt, and mix everything around a bit to let spinach, onions and garlic incorporate, and the spinach cooks down. Watch closely so that garlic does not burn.
