Thanks guys!!!

What about if say I did get a burger like a chicken burger or a fillet o fish (yum) what about the sauce it has on it? Would that be a creamy whole egg mayo? Or shouldnt I worry about little things like that! I want a fillet o fish! WITH the sauce! lol.
I doubt a fast food outlet would be using good quality whole egg mayo. Have a look at their website, there should be ingredient listings for all their products.
