I don't take credit for coming up with the idea for that Big McChicken, it's from the McDonald's secret menu, so I built one, and had it. But I just got into my old photobucket account and found something you guys might find interesting. This is at least 4-5 years old...but...
It's essentially a McGriddle Mac, with a bacon egg and cheese on top of a sausage egg and cheese. I don't remember it being particularly good, and prefer the aforementioned double sausage egg and cheese mcmuffin.
