what you need:
petit beurre biscuits
lindt dark chocolate
vegan marshmallows

what do do:
preheat oven (top grill) to 200°C. add some biscuits  with marshmallows on top. i cut my marshmallow in half as they REALLY expand in the oven. when the marshmallow begins to brown, take everything out of the oven, add the chocolate and top biscuit, wait for 5 sec till the chocolate melts, and take a big bite.
