Chill 2 glasses in the freezer for 15 minutes. Meanwhile, combine the salt and lime zest on a small plate. Remove the glasses, rub the rims with a lime wedge to wet, then dip rims into the salt/zest mixture.
Pour all the liquids into a blender and blend briefly to combine. Add the frozen mango chunks and a generous amount of ice cubes and pulse until a thick consistency is reached. Pour mixture into glasses and enjoy!
