Make this for a large party or halve the recipe for a family meal. Cutting and pounding the chicken to make it wide and flat is easy, but explaining it is hard. Search for step-by-step visual instructions online. Note: this recipe calls for romesco sauce (recipe follows), so plan accordingly. You won't want to use store-bought romesco (if you could even find it), because it often contains breadcrumbs and is not gluten-free.
