Several other reviewers noted the extreme amount of mayo.
You can also find good options at Whole Foods and Trader Joe's.
THis was good!! I made a few changes -- I used white bread and Famous Dave's Hellfire Pickles, because that's all I had -- but I don't think either of those made much of a difference, beside the obvious.
When I made this according to the recipe, I did not like the amount of mayo.
