In a medium bowl, combine the bulgur and the water. Cover and let sit for 20 minutes.
In a large nonstick frying pan, heat 1 1/2 tablespoons of the oil over moderate heat. Add the corn and 1/4 teaspoon of the salt and cook, stirring occasionally, for 5 minutes. Add the onion and continue cooking for 5 minutes longer, stirring occasionally. Transfer to a large glass or stainless-steel bowl and let cool.
Add 1 tablespoon of the oil to the frying pan and heat over moderate heat. Season the chicken with 1/4 teaspoon of the salt and the black pepper. Cook the breasts until browned and just done, about 5 minutes per side. Remove the chicken from the pan and let it rest for 5 minutes. Cut crosswise into 1/4-inch slices.
Add the bulgur, tomato, jalapeño, cilantro, 3 tablespoons of the lime juice, the cayenne, and 3/4 teaspoon of the salt to the bowl with the corn and onion. Toss.
In a small glass or stainless-steel bowl, combine the remaining 1 tablespoon lime juice, 2 tablespoons oil, and 1/4 teaspoon salt. Mound the salad onto plates. Top with the chicken and drizzle the chicken with the lime oil.
Wine Recommendation: German rieslings show their great adaptability by flattering notoriously difficult-to-match salads. The earthy flavors of a young Pfalz spätlese will match those of the sweet corn and chicken.
