I feel like that’s a grey area because it’s called salad but only in the context a product with dressing (the mayo). but it’s not really a salad, it’s just called chicken salad the way Kraft dinner isn’t really a dinner but it could be a dinner. I say if it only has chicken and mayo, that’s not a salad, that’s a sandwich filling. If it has celery, onion, etc, you could make the argument it was salad.
