I don't get the obsession over the chicken big mac, I can't stand the chicken sandwiches in there anyway, tiny amount of chicken, tasteless, greasy and then loaded with mayo, you can make one much much tastier and better for you at home, M&S do beautiful buttermilk chicken portions, crisp them up in the air fryer and have them with crispy lettuce on a decent bread option...yum! Im partial to a cheeseburger now and again but im not a maccies lover at all. Thought she couldn't even manage to finish a big mac meal anyway????
