Mix first 4 ingredients in large bowl.
Take filo dough from package; lay flat on counter and cover with damp cotton towel to keep from drying.
Cut one sheet of filo into 4 lengths.
Put teaspoon of cheese mix on each strip and fold into triangle shapes (like you would fold a flag).
Place onto cookie sheet and dab with melted butter.
Bake at 350 degrees until golden brown (can be made in advance, then covered with wax paper and stored in the refrigerator - or frozen).
