Apple Flax Seed Squares

Preheat oven to 375 degrees. Lightly spray a 15-by-10-inch baking sheet with nonstick cooking spray.

In a large bowl, mix together flour, salt and flax seed. Cut in shortening until mixture is crumbly. Stir in egg yolk/milk mixture until soft dough forms. Divide dough in half.

On a lightly floured surface, roll 1 half into a 15-by-10-inch rectangle to fit the baking sheet. Place rolled out dough on prepared baking sheet. Sprinkle cornflake crumbs on top.

Place apple slices on top of crumbs. Sprinkle white sugar and cinnamon on top.

Roll other half of dough on a lightly floured surface to the same size. Lay on top of apples to cover. Crimp edges all around to seal.

Beat egg white until frothy. Brush on top of crust.

Bake at 375 degrees for 35 to 40 minutes, until golden brown. Cool.

In a small bowl, mix together powdered sugar, water and vanilla (or almond) extract. Stir well, adding a few drops of water if needed. Using a spoon, drizzle icing on top.
