Cut the watermelon into small cubes. This can be done many ways, but the video above shows my favorite method. I have also julienned the watermelon, and that made for a beautiful salad as well.
Julienne the jicama. I do NOT suggest cubing it. Jicama is a nice, subtle touch if added in small bites. However, it can be too much if the bites are too large.
Make the dressing by adding the mint, lime juice, salt, vinegar (or lime zest), and honey and mixing.
Add all ingredients together and refrigerate to cool. Eat at any time.
