This zesty little appetizer is going to have everybody at the party guessing the secret ingredient. It doesn't get that creaminess from avocado, or that crunch from edamame. Give up? It's hearts of palm. The core of the tropical plant is mild and sweet, with a tender bite similar to that of artichoke hearts. No need to mention it's super-healthy. Just set it out with some chips and crudités, and bask in the compliments!
