a work surface with
a short side of phyllo nearest you, keeping remaining
sheets covered,
and brush with some butter. Top phyllo with 3 more
sheets of phyllo,
brushing each with butter. Arrange bananas one

horizontally, on lower third of phyllo, leaving
a 1-inch border on
both sides (trim bananas if too long). Sprinkle
chocolate over
bananas, then fold sides of phyllo toward middle
(over ends of
bananas). Fold bottom edge of phyllo over bananas
and roll up bananas
in phyllo.
