Line a Microwave-Safe Plate with several sheets of papertowel. Place the pepperoni slices in a single layer.

Microwave for 30 - 60 seconds (depending on the wattage of your microwave). The pepperoni slices should be nice and crispy and most of the grease absorbed on the papertowels.

If any in the center are not crispy looking and still feel soft, microwave more in 15 second increments.

Salt if desired.
