Blackberry and watermelon might sound like a crazy combination, but the smoothie turned out very well so I'd like to share it with you. It was actually more of a drink than a smoothie and it didn't last me all morning, but the taste is very refreshing because of the watermelon.
1 large handful of blackberries
1 quarter of a watermelon
I didn't add any kind of sweetener or power foods, but you can do that if you so desire. Mix the ingredients in a blender and pour in a large glass. Enjoy!
