To prepare the dough, roll up the flour, salt, olive oil and water until the dough becomes spongy and elastic. Then roll out the dough on a surface which should be covered with flour until the dough is very thin. Place the rolled out dough on four round, or one square baking tray. The baking tray(s) should be lightly greased. Slightly pull up the edges of the dough.
Now to the topping: Slice the VEGANSLICES into thin long strips, cut up the onions in to thin slices. Halve the bulbs of fennel (but cut the stem off!) and also cut them into thin slices. Cut the pepper into quarters, remove the seeds and also cut into thin slices. All ingredients for the topping should be lightly braised.
Stir the soya cream together with some grated lemon peel, the oats and add a little salt and pepper. After mixing these together, lightly spread this across the dough. Add the VEGANSLICES and toppings. Make sure to spread the topping evenly.
Bake the tarte flambée in a pre-heated oven (at 200°C) for about 15-20 minutes. It will be ready when the dough is nice and crispy.
