Run a lemon wedge around the rim of four glasses, then dip the rims into salt.
In each glass, add ice, pink lemonade, lemon juice, triple sec, and tequila. Stir well to mix. (If you like lots of ice, you can stir the mixture separately before pouring it over the ice.)
Garnish each glass with a lemon slice and enjoy your refreshing Señorita cocktail!
