HG's Magical 100-Calorie Margarita

Haven't tred this yet but I'm really looking forward to giving it a try this weekend.

INGREDIENTS
6 oz. Sierra Mist Free (or Sprite Zero, or your other fave no-cal lemon-lime soda)
1 shot of tequila (1.5 oz.)1 packet
Crystal Light on the Go Lemonade (you may use 1/2 of the packet if you don't want your drink as intensely sweet)
2 tbsp. lime juice from concentrate (or fresh-squeezed lime juice)

DIRECTIONS
Mix all ingredients together. Pour over 1 cup of crushed ice. Enjoy.

You can also make your margarita alcohol-free. This recipe, without tequila, contains just 10 calories (5 calories if you use only half of the Crystal Light packet).

1 tsp. Crystal Light Lemonade drink mix may be substituted.
