This is my favorite skinny margarita.
In a cocktail shaker add ice.
Add Tequila, Grand Marnier, and Margarita Mixer
Shake until the shaker is frosty.
In a glass pour margarita over ice.
Take the lime wedge and squeeze juice over the top of the margarita.
Garnish with a slice of lime.
Amazon has the Lite Margarita Mixer here.
Because this is a skinny cocktail I do not rim the glass with sugar.
If you like your glass salt rimmed, go for it!
