Into a blender, add frozen lime concentrate.
Using the can that the concentrate was in, add a few ounces of your sprite zero. Add in the cherry lime drink mix package. Stir the mix into the sprite until it is well blended.
Top off the cherry lime mix with the remaining Sprite Zero (you will have 12 oz of Sprite total)
Pour the Sprite zero mixture into the blender followed by tequila.
Finally add ice into blender. Blend all of the ingredients until frozen margarita consistency is seen (about 2 minutes)
If you are going to add a salted rim to your glass: Place lime juice into a small plate. Next place your glass onto the plate allowing the rim to become wet. Finally roll the rim into margarita salt.
There are 2 options for serving:
1) Pour half of a beer into the bottom of your glass then top with margarita.
2) Pour half a glass full of margarita & place a beer into the glass so that the beer slowly flows into the drink while your consume it.
Serve & enjoy!
