My "Faux" Margarita/Cocktail for the Summer

Now I just love margaritas. Especially ones made with silver tequila and Grand Marnier. But it gets expensive and heavy on the calories...so I have to come up with my own! I do a classic "skinny girl" margarita with just tequila, lime juice and a little stevia/agave mix to sweeten it up. On the rocks in a glass rimmed with Kosher salt...heaven!
But I wanted to come up with other cocktails too....so I'm playing around one day in the kitchen and came up with this:
1 ounce tequila
1 ounce fresh lime juice
1 ounce water
Hansen's Diet Tangarine-Lime Soda (as much or a little as you want!)

I mixed the tequila, lime juice and water over ice in my highball glass, then added the soda to fill. Delicious! And almost calorie free!
It's nice and refreshing...really good on a hot day!
