How to Make It
In a large bowl, combine the jicama, radishes, onion, cilantro, raisins, lime juice, 2 tablespoons of the oil, ½ teaspoon salt, and ¼ teaspoon pepper. Set aside.
In a medium bowl, toss the shrimp, ground chilies, remaining tablespoon of oil, and ½ teaspoon salt.
Heat a grill pan or large skillet over medium-high heat. Cook the shrimp until opaque throughout, 2 to 3 minutes per side. Serve with the salad.
