BK has his worst nightmare with an overly mayonnaised chicken salad.
My least favorite thing is those "salad" sandwiches that are made with too much mayo in the first place, and are RUNNY. Can't stand that. Especially with tuna salad.
I'd rather the mixture be made on the dry side (which I do at home, adding just a little bit of mayo at a time) and requiring some added mayo for lubrication when put on the sandwich. But it's also got to be Hellman's/Best. And of course it shouldn't be dripping, either.
It's a fine, fine line we walk with our foodstuffs.
