Jicama and Orange Salad

In a large bowl, whisk together the lime juice, salt, chili powder and cayenne.

Add the jicama, which is peeled and cut into 1/3-inch strips.

Arrange orange sections decoratively around the edge of a platter and use a slotted spoon to mound the jicama in the center.

Drizzle the dressing remaining in the bowl over the oranges and sprinkle the green onions over the salad.
