Avocado Margaritas

In a blender combine the ice, avocado, tequila, lime juice, triple sec, agave nectar, 1 sprig cilantro, and jalapeno. Cover and blend until smooth.

If desired, rub each of two glass rims with a lime slice or wedge, then dip rims in chile-lime salt. Separate margarita mixture between the prepared glasses and garnish with an additional sprig of cilantro and lime wedge or slice, if desired.
