This deliciously simple delight is perhaps Catalan cuisine's best known dish. In demand from both tourists and locals, it-s the most popular tapa and perhaps Spain's most popular breakfast. An important point to remember is that the original recipe never includes chopped or grated tomato. The authentic "pan con tomate" is toasted bread with a ripe tomato cut in half and rubbed over the bread, some olive oil, and a pinch of salt.
