I dont believe anybody havent thought about this already why Mac Donald doesnt make grilled chicken macnuggets or Wendy or burger king make grilled chicken nuggets that would be good. What do you think?
Chick-a-fil's done it apparently (take a look at the link). As to why McDonald's or Burger King haven't done it, who knows, only the company probably. If you need to know perhaps try sending them an inquiry email or letter.
they have a lot of items they might not think about it yet, good suggestion.
