I was just combining fruit that I had lying around to tide me over til my usual Sunday morning food shopping. It turned out to be an excellent smoothie combo that I'll be making very frequently!! It's nice and warm, too, which I always love with my smoothies.
6 oz. blackberries (just one container)
2 cups of pineapple
water (just enough to blend it though- it tastes amazing with a thick and creamy texture)
Throw it all in the blender and drink.
