Well, it turns out my post regarding Fatburger was factually incorrect. As someone pointed out in the comments, it must have animal products since it has cholesterol. So, on my lunch break and in the Fatburger parking lot, craving a veggie Fatburger, I called them. I asked if the veggie burger was vegan, and the answer was no. It has cheese IN THE PATTY. What the hell? A veggie burger with cheese in it. Why not keep it out of the patty and put it on top if people want it? Well, that's not their style. So I had to go elsewhere that day. And Fatburger lunches are no more.
I'm probably better off anyway without it.
