Vegetarian black pudding and polenta layer

Lots of interesting things from Todmorden's market - polenta and olive oil from The Mediterranean Pantry (that's me), vegan black pudding from Chris outside, veg from Garry outside - and really good Cambozola from the Crumbly cheese.  This was dead easy, and quick.
