Watermelon Cooler

This is all that was left of a LARGE glassful when I remembered
that I should take a picture!

frozen watermelon chunks* (about 1 cup per serving)
pre-sweetened (i.e. Country Time) lemonade mix (about 1 Tbsp per serving)
Sprite (Sierra Mist, 7-Up, etc.) (about 6 oz per serving)

Mix all in a blender. Enjoy!

*Cut fresh watermelon into chunks. Put on a cookie sheet in the freezer until firm. Keep any extras in a Ziplock bag in the freezer for next time!
