Though native to North America - since the 16th-17th century, the cactus plant has spread throughout the world.
While I'm familiar with how cactus leaves are eaten in Mexican cuisine - I've never heard of dishes from other parts of the world that involve cactus leaves. A quick search on Wikipedia - which is always correct - says that cactus is commercially grown throughout North Africa. But I'm not familiar of any cactus leaf dishes. Are there any? Do cactus leaves appear in any other cusines?
