Are your chicken 100%

When going to a fast food restaurants and you order a chicken fillet or burger or beef burger did you know there are fillings in the chicken and beef burger make up the food you eat which means they are not 100% it's a total rip off and you and I are paying for it. Here is a example subway chicken was tested in a lab and it was found the chicken was less than 50% meat compared to chicken in the butcher it composite of vegan filling in the chicken burger and there are other like MacDonald or Wendy's where the chicken is more meaty than subways of over 80% chicken but still not 100 percent.
