We had a fun time here with this dish. After grilling the cigar rolls of minced beef wrapped in betel leaf on a hot pan with butter, we swaddled them with rice noodles, raw beansprouts, lettuce and pickles in sheets of translucent Vietnamese rice paper before stuffing them in our mouths. A word of caution: you have to like betel leaf otherwise you might find its herbal smell and taste quite a turn-off.
