Slice the chicken breasts into finger-shaped nuggets by slicing them horizontally across each breast.
In a small bowl, whisk together egg and lemon juice.
In a medium bowl, combine Rice Krispies, paprika, brown sugar, onion powder, and salt. While mixing, crush the Rice Krispies with your hands.
Dredge the chicken fingers in the egg mixture, and then press very well into the Rice Krispies mixture to coat.
Heat oil in a large frying pan. Add chicken strips, a few at a time, and fry until golden, about 4 minutes per side. The oil will get dirty in between batches from the extra Rice Krispies which fall off the chicken, so add a carrot to the oil to attract the burnt fried bits and keep the oil clean.
