You can’t go to Puerto Rico and not have arroz con habichuelas, or rice and beans. An essential side dish, the rice is cooked separately from the pink beans (or pinto beans), which are mixed with onions, squash, peppers, garlic, and the ever-present sofrito.
You can serve the beans on top of the rice or to the side, though most people mix them in to create a flavorful melange.
The dish is so important to Puerto Rican that the group El Gran Combo de Puerto Rico has an entire album and a single named after it.
