This sugar free margarita has just three ingredients (plus water) and is simple to mix up. Many margarita recipes call for Triple Sec which we have omitted to make this more authentic-- like what you'd drink in Mexico! This also keeps the carb count much lower. This Keto Margarita recipe has just three net carbs and 76 calories per serving. To make this a non alcoholic low carb margarita, simply omit the tequila.
