Because you also need fun in life: Even hardcore paleo fitness fans love this alcoholic drink. For a Norcal Margarita you need:
Take a shaker, or a tall glass that you can temporarily close, and add 2 shots of tequila, the flesh and juice of a lime and crushed ice. Fill with soda, close and shake well. Serve on ice and dilute with soda according to taste and alcohol compatibility.
In nutritional terms, the Norcal Margarita is a flyweight: the drink has just 130 calories, no more than a medium-sized banana. Perhaps not quite as healthy, but more fun than just a piece of fruit. Cheers, guys!
