Add the mango chunks, water, and sugar to a blender and
blend until smooth. If you have
room in your blender, add some or all of the tequila and
triple sec while blending, it will make the next step
easier.
Pour everything from the blender into the
slushie machine. If you didn't add the tequila and triple
sec before, add it now.
Turn the slushie machine on, and hit the frozen spiked slushie or frozen drink
button.
Pour
your margaritas into sugar rimmed glasses and get
ready for the compliments.
