Cut each circle of dough into 16 triangular pieces or wedges.
For filling: Beat egg whites until foamy. Gradually add sugar; beat until stiff. Fold in pecans and vanilla.
Spread 1/2 teaspoon filling on each triangle of dough; roll up, beginning with largest end. Place roll, small end down, on greased cookie sheet.
Bake in a 350 degrees F oven 10 to 12 minutes, or until slightly browned on bottom. Immediately transfer to racks to cool.
Sift powdered sugar over cooled cookies. Store in airtight container. Yield: About 10 dozen cookies.
