Bring oil in pressure cooker over medium heat to about 400 deg F. In a small bowl, combine the egg and lowfat milk. In a separate bowl, combine the remaining four dry ingredients. Dip each piece of chicken into the lowfat milk till fully moistened, then roll in flour mix till completely coated. In groups of four or possibly five, drop the covered chicken pcs into the oil and lock the lid in place. When steam begins shooting through the pressure release, set the timer for 10 minutes. After 10 minutes, release pressure according to manufacturer's instructions, and remove the chicken to paper towels or possibly metal rack to drain. Repeat with remaining chicken.
