3/4 cup (6 ounces) limeade frozen concentrate
3/4 cup gold tequila
1/2 cup (4 ounces) Triple Sec orange liqueur
4 cups crushed ice
1 Mexican lime, sliced
Sugar

Combine all ingredients except lime and sugar in a blender and blend until slushy, adding more ice if necessary.

To prepare glasses, moisten rims with a lime slice and dip in a plate of sugar. Fill glasses and garnish with lime wheel slices.

For a non-alcoholic version, omit tequila and replace Triple Sec with reconstituted orange juice.
