Combine the dry ingredients in a food processor, pulsing about 10 times. Add margarine, continuing to pulse until the mixture resembles coarse crumbs.

Add pareve whipping cream, egg yolk, and zest and process until a dough forms.

Shape the dough into a disc and place in the fridge for one hour.

Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).

Place a sheet of Gefen Parchment Paper on the counter. Put the dough on the parchment and roll out until you have a large circle. The dough should be thin, but you should still be able to handle it. Arrange sliced strawberries in a mound in the center of the dough and fold the sides in.

Place the parchment paper on a baking sheet and bake for 20 minutes.
