I just ate a hot dog on a potato roll. I checked and double checked the list of ingredients, but found no potatoes. The roll didn’t look, taste, or smell like a potato. What gives?
Well, it should be made with potatoes. I believe they are somehow trying to mimic the flavor of Irish Potato Farl.
It’s odd that it didn’t contain potatoes as an ingredient. When I’ve bought them, they’re made either with potatoes or with potato flour. I’ve made bread both ways, myself. Adds an interesting texture.
Ask the place where you bought them, it may have been left off of the ingredient declaration.
If they’re ethereally light and flaky, with a nice earthy/starchy background flavor, they are true potato rolls.
Otherwise, you’ve been ripped off, and I’d follow the advice of the previous posters. 
Yum, potato rolls, love 'em …
Oh man. My grandma makes the best potato bread. It’s even better with peanut butter and (once again, Grandma’s) strawberry jelly.
Mmmmm.
You should turn them in to the FDA. If they do not list the potato as an ingredient then they cannot call them potato rolls.
Unless of course they followed Dan Quayles recipe and called them “Potatoe Rolls”!
