In a mixing bowl combine the mango, jicama, cucumbers, chile, lime juice, and salt.
Toss well, cover and refrigerate for at least 1 hour before serving.
The longer the salad sits, the more flavorful it becomes. A perfect complement to any dish on a sunny day.
I often buy Tajin, the fruit and snack seasoning chile powder sold at our local Mexican grocery store, which has ground chile peppers, salt, and dehydrated lime juice. If you have access to this brand I highly recommend it.
