To Assemble:Unfold phyllo. Using a sharp knife, carefully cut phyllo sheets crosswise, into thirds. Cover phyllo not being used with a barely damp towel. Using two pieces of phyllo - phyllo sheets are so thin they must be doubled - and keeping narrow ends towards you, brush with butter. Place 1 to 1 1/2 teaspoons filling 1/4 inch from end nearest you, to within 1/4 inch of sides. Fold long sides in 1/4 inch. Fold over bottom to cover filling.
Push both ends toward center and remove pencil. Place roll on cookie sheet and generously brush with butter. Repeat with remaining filling and phyllo.
