How are Boneless Wings Made
Well; boneless wings cover a wide breadth of different styles; so no one size fits all answer.


Breaded breast meat or chicken tenderloin breaded; probably the higher end version.
The hotdog of chicken; chopped up leftovers formed into shape and breaded.  Basically a big chicken nugget with more texture to meat.
Plethora of a mixture of above


Ironically they usually don't contain any chicken wing meat.
