The chicken fillet on chicken has two parts, one is the strip on chicken breast and the other is the strip on chicken leg.

There are only two pieces of meat on the chest to make chicken fillet. Others are not.

In addition, there is also a name called "boneless chicken fillet". This kind of chicken fillet is limited to chicken breast, not to those two meats. It can be a whole piece of chicken breast, but "boneless chicken fillet" is a chicken fast food that is pickled, breaded, fried and quickly frozen.
