Did Vikings eat sandwiches?

Did Vikings eat sandwiches? Fish, especially herring, often stood on the menu when the Vikings sat down to eat. They ate lots of stockfish and dried fish too. They also ate whales and seals. And believe it or not, they ate sandwiches made from thick slices topped with a type of butter, and meat of wild boar, deer, elk or bear.
