Trim chicken breasts and cut into desired size nuggets or fingers.
In a large bowl whisk together pancake mix, 3/4 c. water, hot sauce and salt & pepper. Add more water to thin if needed. (Note: You want the mix to be a little thinner than you would for making pancakes, but not very much.)
Heat oil in a fryer or in a medium-sized pot. Add chicken pieces to the batter and stir to coat completely.
When oil is hot, use a slotted spoon to transfer chicken from the batter to the oil. Depending on the size of chicken pieces, only cook about 5 to 10 pieces at a time.Cook about 3 – 4 minutes per side, until batter is browned and chicken is completely cooked.
