Cream margarine, sugar and eggs til light and fluffy. Add flour and lemon juice. Spread in greased jelly roll pan. Strike off 20-24 squares with a knife. Put 1 tb. Fruit pie filling in middle of each scored of square. Bake for 30 min. At 350 When cool, sprinkle with powdered sugar before serving. Pretty and quick. Easy. I use Blueberry on half and cherry on the other half.
