In a shallow bowl, combine lemon juice, hot sauce (or chili oil) and a pinch of five spice powder. Add chicken thighs and turn to coat. Set them aside and allow them to stand for 5 minutes.

To serve, evenly arrange chicken and small piles of the salt/spice mixture on dinner plates. To eat, dip the chicken into the salt/spice mixture. Enjoy!
