Slice a lime into wedges and rub one wedge on the rim of the glasses. Dip the glass upside down in the salt to rim the glass.
Put lime juice, tequila, triple sec, sliced peaches with juice from can, frozen peaches, 7-UP, minced ginger and ice into a blender. Press the On/Off button then press the symbol for icy drinks (it's the center symbol). It will run a program that will blend the margarita.
When the blender stops, pour out the margarita into the prepared glasses. Garnish with a lime slice and enjoy.
