Combine all ingredients in a blender with 1 cup of ice and blend for 20 seconds. Pour into a cored pineapple and garnish with fresh mint.
Slice the top of the pineapple off a half-inch from the top. Core the inside of the pineapple. Don't have a pineapple corer handy? Core your pineapple with an ice cream scoop! Make sure you don’t scoop all the way to the skin or your pineapple will leak.
