In a medium bowl, combine corn starch, spices, and flour (if not GF).
Stir gently with a fork.
Add chicken and toss to coat, making sure there is a dusting on all sides of each piece.
Transfer chicken to a mesh strainer to get rid of the excess flour. Set aside.
In a large skillet, add enough vegetable oil to coat the bottom of the pan. Heat until a drop of water sizzles in the pan.
Working in batches, add chicken pieces, giving a quick shake before dropping in.
Try to make sure the pieces are in a single layer and NOT touching each other.
Once cooked through and brown remove with a slotted spoon and place on a paper-towel-lined plate.
IMMEDIATELY sprinkle with salt.
Repeat in batches until done.
*If you prefer to bake the nuggets instead, spread out dusted chicken on a sheet pan and bake in 400 degree oven for about 30 minutes, flipping once about halfway.
