Add about 3 cups of frozen water melon
Cut strawberries like so. I used 6 in mine
Blend on ice crush (pulse) after that, add 1 row of ice cubes from your ice tray. Blend again.
You can add more watermelon/strawberries according to your taste, you can also add a bit of sugar if you want it sweeter, I didn't.
There's your healthy, refreshing drink! :)
