Add all ingredients into a cocktail shaker with 1 cup of ice. Shake, shake, shake!

To make a salty rim, pour about 1 tsp lime juice per drink you're making into a small plate. In another plate, cover it in Kosher or flakey salt. First, twist your glass in the lime juice, next twist it in the salt. Voila!

Add ice to your cup, then pour in your Skinny Grapefruit Margarita! Serve with a wedge of grapefruit on the rim. Enjoy!
