Oooo I have a drink recipe with watermelon. After all this talk last night I bought a whole watermelon at the store and we made drinks.
Non-alcoholic
Watermelon chunks (seeds can be it), ice and grenadine
Put in the blender and blend til smooth! My prego girlfriend and the 2 kids sucked down the whole blender full! They LOVED it!
Alcoholic
blend up chunk of watermelon into juice. Put in a shaker with grenadine, ice and watermelon vodka. Shake and pour into martini glasses.
OOOOHHHH sooo yummy ladies!

We made both last night and it was soo yummy!
I was also thinking, you could blend up watermelon and pour it into popsicle molds and freeze it for a healthy all natural popsicle. And you can blend it seeds and all (well the little white seeds).
Let me know if you girls (and guys) decide to try any of this, how it is! We all really liked it!
