Roll out dough to one- quarter-inch thickness. Cut into three- and- a- half-inch squares.

Combine all ingredients for filling, mashing very finely.

Place one heaping tablespoon of filling in center of each square. Fold dough over filling. Place seam-side down onto lined cookie sheet.

Brush with egg, sprinkle with sesame seeds.

Bake at 350 degrees Fahrenheit for 40 minutes or until delicately golden.
