Arrange jicama slices on a platter and pour the lime juice over.
Sprinkle with chili powder and salt to serve.
Note: The jicama can be tossed with the lime juice, chili powder, and salt & refrigerated for several hours before arranging on a platter. Cover with plastic so the jicama doesn't dry out. Sliced jicama can also be held in a bowl of water in the refrigerator for a couple of days.
