You will see Catalan tomato bread at many restaurants and tapas bars in Barcelona—and that’s a very good thing, because it is insanely delicious for such a simple preparation. Grill bread. Rub with tomato. Drizzle with oil, sprinkle with salt. That’s it. Of course, you’ll need really good bread. And, for maximum impact, you’ll need really ripe, red tomatoes. But remember, pa amb tomàquet is not bread with tomatoes on it; it’s more like bread painted with tomatoes. Once the painting is done, you could add a few flourishes to the canvas, as the Catalans do: slices of ham, anchovies, fine canned tuna in olive oil. Or you can eat the slices all by their blessed selves. Bring the first batch to the buffet table at the start of the party; it can stand for quite a while.
