Combine tequila, triple sec, limeade mix and ice in a blender.
*opt for the generic frozen limeade mix vs. those fancy brand-name frozen mixers
*don't skimp on the tequila if you don't have to - any mid-to-high range tequila is preferred
Blend until smooth.
Take a quarter of your lime and make a slice down the middle on the pulp side. Then run the lime around the rim of your beverage glass.
Pour salt on a small plate or dish, larger than the diameter of your glass.
Place glass in salt and rotate rim of glass until covered.
Pour frozen margarita into glass and enjoy!
