New Allison'S Mambo Margaritas - cooking recipe

Ingredients

12 ounces frozen limeade concentrate (do not thaw)
12 ounces Corona beer (or other light beer)
12 ounces carbonated lemon-lime beverage

Preparation

Dump limeade into a large pitcher.
Stir in rest of the ingredients, using the can from the limeade to measure the soda and tequila.
Serve in glasses rimmed with salt, if desired (I like them salt-free).
