Peel watermelon & chop into chunks & add 4 dessert spoons of Splenda.

Add juice & zest of lime plus a few chopped mint leaves (mint is optional).

Blend together, put into shallow dish & freeze.

After about an hour brake up with a fork, re-freeze for another hour & repeat.

If in freezer overnight let it defrost about half an hour before serving.
