They may be accaeptable, but it is hard to tell bc they rarely post a full list of ingredients. Plus, the mayo is most likely full fat bc of the money factor (full fat is much cheaper than low/no fat when purchased in bulk).
I would make my own if I were you.
I make mine with spices, chopped onion and peppers, and with mustard and good seasons italian dressing instead of mayo.
Good luck!
