Preheat the broiler. Put the chicken between 2 sheets of waxed paper and pound with a mallet or hammer so the chicken is an even thickness of about 3/4-inch, then cut the chicken crosswise into 1/2-inch strips. In a large bowl, combine the hot sauce
and the oil, add chicken and toss until the chicken is well coated. Arrange the chicken on a baking sheet and broil
until it is cooked through, about 4 to 6 minutes, turning once.
In a large bowl combine the Romaine, celery, shredded carrots and scallions. Toss with the dressing. Divide the greens between 4 plates, top with the chicken. Serve with extra hot sauce.
