Gazpacho is a refreshing cold soup that is perfect for the hot summers in Madrid. It is made with ripe tomatoes, cucumbers, bell peppers, onions, garlic, olive oil, and vinegar. The ingredients are blended together until smooth, and the soup is then chilled before serving. Gazpacho is a light and healthy dish that is packed with flavor. It is often garnished with diced vegetables and served with a side of crusty bread. Many restaurants in Madrid offer gazpacho on their menus, including those near the Royal Palace.
