In a large pitcher, muddle together mint, sugar, pinch salt, and lime juice.
Add Watermelon Agua Fresca and tequila, stirring to combine. Add ice to fill the pitcher.
To serve, fill a glass and garnish with watermelon, mint or lime as desired. If you really want to get fancy a sugar and salt rim on the glass would be a nice touch. Enjoy!
Notes
To make this beverage more like a spritzer; add some club soda or lemon lime soda.
