Mix sugar, oil and margarine. Add eggs and juice and mix well. Blend with dry ingredients and roll into a ball. Divide into four parts. Roll out each piece very thin (approximately 1/8 inch) on a floured board. With the rim of a cup or glass (depending on desired size) cut into the dough to make circles.

Place 1/2 to 2/3 teaspoon of filling in the middle of each circle. To shape into triangle, lift up right and left sides, leaving the bottom side down, and bring both sides to meet at center, above the filling. Lift bottom side up to center to meet other two sides. Preheat oven to 350 degrees. Brush dough with beaten egg before baking. Place on greased cookie sheet. Bake at 350 degrees for approximately 20 minutes.
