Crumble feta cheese and add pot cheese, blending well. Add eggs and
beat thoroughly. Melt butter. Carefully cut pastry into 3 equal
portions. Refrigerate 2/3 of pastry until needed cover the rest
with a damp towel. Remove one sheet of pastry, place on a flat
surface and butter well. Fold in the long sides toward the middle,
making a strip about 2" wide, and butter again. Place 1 tb cheese
mixture in the bottom right-hand corner of the strip and fold over
into triangle shape. Continue folding, making sure that with each
fold the bottom edge is parallel with the alternate side edge.
Lightly butter the finished triangle. Continue until all the cheese
is used.
Bake triangle puffs in a 425?F oven for 20 minutes or until golden
brown, turning once. Cool 5 minutes before serving.
