Barcelona is famous for the ingredient-rich dishes, but their simplest may be one of the best. Pa Amb Tomáquet is merely stale bread, tomato, and olive oil. Farmers would make this dish to avoid wasting the stale bread and softer tomatoes. It is called Pa Amb Tomáquet, and not Pan Con Tomate, because this dish originates from the Catalan language. This dish is served in restaurants throughout the region as an appetizer and in nearly every home as a common snack. Normally, it is served with a side of various cuts and styles of serrano ham; however, the best versions of this meal feature roasted garlic spread on the bread before the tomatoes. If you’re ever in the mood for a light and simple snack, this Barcelona staple will fulfill your needs.
