In Belgium you can buy the vol-au-vegan at Veggie Deluxe.
Traditionally you serve ‘vol-au-vent‘ in puff pastry ‘bowls’. But I couldn’t find any vegan ones. So I did a bit of improvisation.:
Ready-made puff pastry is fortunately easy to find.
Take one sheet, cut it in half through so you get two rectangles.
Mix a little soymilk with some besan (chickpeaflour).
Spread this mix on one of the rectangles.
Then sprinkle with some poppy seeds.
You can also use sesame seeds.
Bake the puff pastry in the oven as instructed.
Place the bare rectangle on a plate, cover with vol-au-vegan and then cover with the poppy seed pastry.
