Preheat the oven to 400 degrees.
Cut 1 inch lengthwise away from the dough to use for decorative cut-outs; set aside.
Lay one sheet of vegan pastry dough on a flat floured surface like a countertop
Using a rolling pin, roll until even and about twice the size as the original dough.
Place the vegetables mixed with ½ cup gravy in the middle, lengthwise on the rolled-out dough.
Fold both vertical ends, and then fold one side over the other side horizontally, sealing the vegetables inside the dough.
Place a silicone mat or parchment paper on a baking sheet.
Gently flip the vegetable strudel seam side down onto the lined baking sheet.
Using a cookie cutter, use the 1 inch of dough to cut out shapes using a small cookie cutter ( I used a heart shape).
Vent the strudel using a knife and make slits down the strudel so the strudel can breathe while cooking.
Bake for 30 minutes, uncovered.
Remove the strudel from the oven and allow it to cool.
Serve with masked potatoes, a salad, or your favorite side.
I drizzled with additional gravy and made mashed potatoes and gravy.
