This traditional recipe is perfect for breakfast, lunch, or dinner and can be enjoyed warm or at room temperature. The combination of tender potatoes and sweet onions with fluffy eggs makes this dish a favorite in Spanish cuisine.
Most of the ingredients for this recipe are common and likely to be found in your kitchen.
