Pineapple Watermelon Slush

"Pineapple Watermelon Slush is a refreshing summertime drink. You can make it into a cocktail too by adding your favorite kind of liquor! This Pineapple Watermelon Slush was such a hit and a great way to cool down when the weather is hot. There is NO added sugar in this, and it was perfectly sweet. Cube up some watermelon to start. I like to remove all the rind from my melons before slicing them, but it isn’t necessary. As long as you end up with rindless chunks at the end, you can cut up your melon however you want."
