Hearts of Palm are an interesting vegetable. They are, as the name suggests, the center of certain types of palm trees, and considered a delicacy. Heart of Palm doesn't have much flavor by itself, but it goes wonderfully with onions. Some people also put them with salads or fruit.
This dip pairs heart of palms with green onions for a really delicious treat. I highly recommend serving with pita chips or bread!
This is the recipe which inspired my Heart of Palm Sandwich.
