Preheat the oven to 375° F.
Prepare a 13X9 baking sheet with parchment paper and set aside.
In a small mixing bowl, mix up the egg substitute and set aside.
Combine flour, sugar, and salt into a medium sized mixing bowl.
Add the vegan margarine, and mix until the margarine is well combined.
Next add the egg substitute and oil to the medium mixing bowl and blend.
Now add the water, 1 Tbsp at a time, mixing with each Tbsp.
If the dough will not stick together, add 1 to 2 Tbsp of Olive oil, mixing after each to make sure not to over moisten. Do not add more water.
Form the dough into a ball and cut in half.
Prepare a floured surface with a rolling pin.
Place 1/2 of the dough ball onto the floured surface and begin rolling out the dough.
Roll out the dough to about a 1/4 inch thickness.
Cut the dough into rectangles, about 2x3 inches in size. (You are more than welcome to cut your pastries into any shape or sizes you would prefer.)
Carefully place the rectangles onto the baking sheet. (These will not spread, no need to space them too far apart.)
Continue rolling out the dough until the baking sheet is full.
After the first half is rolled out and placed on the baking sheet, set this aside.
Place the other half of the dough onto the floured surface and roll it out to about 1/4 inch thickness.
Cut the dough into rectangles, you will be using these on the top of the filling.
