Divide the lettuce among 4 individual plates, cover and set aside in a large bowl. Combine the chili powder and cumin. Add the chicken, turning to coat. Lift the chicken from the bowl, shaking off the excess coating. Dip the chicken into the egg whites, then coat again with the remaining dry mixture.
Heat the oil in a wide nonstick frying pan or wok over medium heat. When the oil is hot, add the chicken and stir-fry gently until no longer pink in the center. Cut to test (5-7 minutes). Remove the chicken from the pan and keep warm. Pour the salsa into the pan: reduce the heat to medium and cook, stirring, until the salsa is heated through and slightly thickened.
