Mom had the Turkey Terrific which is essentially Thanksgiving between two pieces of Portuguese bread - turkey, stuffing, cranberry and mayo.
I had the Other Turkey with avocado, bacon, pickled shallots, horseradish mayo and arugula on herb bread. I wish I could have ordered 6 more to last the week. I did order the almond butter and cherry jam on Portuguese bread to eat that night for dinner. I have dreams about the turkey sandwich.
Black-Eyed Susan's was open for the week we were there and it's kind of famous on Yelp at least for good brunch. It was fine. I was just really impressed with the breakfast sandwich I ordered. It looks fine, right?
But then I opened the other side and realized all of the bacon. It became all that much better.
Moral of the post - visit Nantucket when Provisions is open and bacon makes everything better.
