Transfer the pretzel flour to a third wide, shallow bowl. Line up the flour, egg and pretzel bowls in that order.
Season both sides of the chicken lightly with pepper. Dredge both sides of chicken in the flour, then the egg, then the pretzel flour, coating well and shaking off the excess.
Spread oil evenly in a jelly-roll pan, and arrange chicken in a single layer in pan and turn over once to coat both sides lightly with oil. Bake, turning halfway through, for 15 minutes, or until lightly browned and cooked through.
Meanwhile, in a small bowl, mix the mustard and apricot preserves; set aside.
Divide the chicken tenders among four dinner plates and serve with the dipping sauce.
