The bread is toasted multigrain, but I always order mine untoasted (I love toast, but hate eating sandwiches on toast - it tears up the roof of my mouth!) I don't really know the ingredients, but the tuna is very good, it is all white, there probably is celery and onion, but if so it is minced up very well, not detectible chunks, KWIM? There is lettuce and tomato on the sandwich too. I get the half sandwich and bowl of clam chowder - the soup is excellent too.
