I can't remember the last time I had mayo Chris
Panera and the associated chains have gotten smacked by nutritionists lately for smearing huge blops of mayo and mayo sauce on ALL their sandwiches, which blows any "healthy" notions away. Granted, it's educated consumers, but some of the hot sandwiches are premade and not available without the sauce.
That, and their nutritional information says, in tinytinytiny letters, "half sandwich". So when you see 550 calories, you think it's the sandwich, not realizing that's only HALF, and it's really 1100 calories.
I agree, mayo in moderation is okay, (I just don't personally like it) it's just that a lot of people will go eat Panera every day for lunch, and probably don't realize how much of it they're eating.
