                        ***FOR THE CHICKEN***
   2                    chicken breasts, boneless, with the skin -- halved
     1/2  cup           fresh lime juice
   1      teaspoon      dried oregano -- crumbled
                        vegetable oil for brushing the chicken
                        ***FOR THE TORTILLA CRISPS***
   4                    corn tortillas -- cut into long
                        triangles
                        vegetable oil for frying the tortillas
   2      cups          cooked fresh corn kernels*
   1      large         red bell pepper -- diced
   3                    scallions -- sliced thin
   2      tablespoons   fresh lime juice -- or to taste
   1      tablespoon    fresh oregano or 1 or to taste -- finely chopped
   1      teaspoon      crumbled dried
     1/2  teaspoon      ground cumin -- or to taste
     1/4  cup           olive oil
   1      bunch         arugula -- washed well, spun
                        dry

Preparation:

* cut from about 4 ears Prepare the chicken: In a bowl let the chicken marinate in the lime juice with the oregano and salt and pepper to taste, covered and chilled, for at least 30 minutes or up to 1 hour. Drain the chicken, pat it dry, and brush it with the oil. Grill the chicken, seasoned with salt and pepper, on a well-oiled rack set about 6 inches over glowing coals for 6 to 7 minutes on each side, or until it is just cooked through. (Alternately, the chicken can be grilled on top of the stove in a ridged grill pan over moderately high heat for about the same length of time.) Transfer the chicken to a cutting board and let it stand for 10 minutes. Make the tortilla crisps while the chicken is grilling: In a heavy skillet heat 1/2 inch oil to 375F. on a deep-fat thermometer and in it fry the tortilla triangles in batches for 45 seconds to 1 minute, or until they are golden, transferring them with a slotted spatula as they are fried to paper towels to drain and sprinkling them with salt. The tortilla crisps may be made 1 day in advance and kept in an airtight container. In a large bowl combine the corn, the bell pepper, and the scallions, add the lime juice, the oregano, the cumin, the oil, and salt and black pepper to taste, and toss the mixture until it is combined well. Cut the chicken lengthwise into thin slices and add it to the corn mixture with any juices that have accumulated on the cutting board. Divide the arugula and the tortilla crisps among 4 plates and mound the chicken salad in the center of each plate.
