Prepare the Glasses
Place the chile lime seasoning in a shallow dish or spread in a small pile (shape depends on glass) on a clean cutting board. Rub a slice of lime around the rim of each glass. Turn glasses over and place directly in the pile seasoning; twist and turn it so the rim gets coated with seasoning.
Blend the Mangorita:
Place mango, 1 tablespoon lime juice, mango margarita mix, tequila and ice into a blender. Pulse several times until mixture is well blended and slushy.
Pour into chile-lime rimmed glasses, garnish (optional), sip back and revel.
