I'm not sure if dish identification is on-topic with this site, so feel free to correct me if it isn't.
I have some older German-descended family members who make a traditional dish I would like to find more information on. The dish itself is pretty basic. A simple egg/flour-based bread dough is flattened, sliced into triangular or freeform pieces, shortly boiled in water, and then fried in oil. The bread can sometimes be salted or contain other seasoning. The bread is served with minced and fried Tuna patties or other Tuna dishes, and is eaten with the fish, often with lemon juice sprinkled onto the bread and fish. Its a dry and savory/sour dish, meant to be shared by a group. Ive also been told it was a dish made during impoverished times.
My family members say this dish is called (a word I don't know the spelling of, neither do they) something that sounds like Nymph or Nypp / Nyff (closest German word I can find is Kniff). Its a recipe that has been passed orally through a couple family lines so the actual word may be lost. For the life of me I cannot find information about this dish anywhere on the internet. Ive described the dish, searched dishes made by the locals, searched for dishes prepared in a similar manner, but I can't find anything that matches the description of it.
I was curious if any well-known traditional dishes matched or were similar to this.
