Place frozen watermelon into food processor

Process until watermelon is completely chopped up and looks like a snow cone - which is pretty awesome in itself

Add yogurt, honey, and lime juice

Process until smooth

Pour into a loaf pan or other freezer container

Freeze for at least four hours, stirring every hour until completely frozen

This freezes pretty solid, so you'll want to take it out of the freezer and let it warm up 10 - 15 minutes before serving
