It may look like a chicken breast, but anyone with a food allergy has realized the ill effects when eating this so-called protein at McDonald's. I have had many clients go to McDonald's (unwillingly) for group outings. They order the GRILLED CHICKEN SALAD with no dressing (because they weren't sure if there was wheat in the dressing) and they still get sick from wheat consumption. Why? Well, the 'chicken breast' is anything but just chicken!
