In a blender, combine watermelon, tequila, lime juice, and Triple Sec. If you didn't refrigerate your watermelon in advance, add 1 cup of ice. Blend until smooth. Taste and adjust according to your liking.
Wet the rim of your glasses and dip in salt. Stab watermelon balls on a toothpick and top for garnish. (Optional)
Notes
