July 4th: Watermelon Frosties

I found the recipe for watermelon frosties here.
You can make two large slushy drinks with these, OR you can fill little lime halfs for an after dinner dessert.  This makes about 20 lime halves.  I love this recipe because so much of it is natural.  I also love it because I always have soooo much watermelon left over, and in doing this, I realized you can actually freeze watermelon and drink it later.  I know, the saying is 'As American as Apple Pie'....but watermelon is actually the treat that accompanies me most frequently on a July 4th picnic....I guess maybe America doesn't have exclusive rights to the watermelon?  (As if we own the apple pie, but don't tell the Apple Pie Quote lovers that...)
OK...I think that covers my thoughts on fruit related patriotism for the moment.  Here's the recipe for Watermelon Frosties
Ingredients:

2 1/4 c. frozen watermelon cubes, 1 1/2 c. water, 2 T. maple syrup, 1 lime squeezed (this is where some of my halves came in, I used the rest for key lime pie).  1 1/2 frozen banana (do NOT leave it in the peel, this was a pain  to get off, just chop it up and freeze it).
\Instructions:  Blend the ingredients.  I then scoop out as much of the innards of the lime, topped with chocolate chips for seeds, and placed these in the freezer until I served.
