COMBINE 3 cups frozen mixed vegetables, 1 can (10 oz / 284 mL) cream of celery soup, 1/4 cup water and 3 coarsely chopped simulated chicken veggie burgers in a bowl.
FILL a 9-inch deep dish frozen pie shell with vegetable mixture. Top with a second, inverted, deep dish pie shell and remove aluminium pie plate. Pinch pie edges to seal. Cut several slits in the top crust to permit steam to escape.
BAKE at 400°F for 35 - 40 minutes or until golden brown. Let stand 10 minutes before serving.
