Basically, you make up a batch of bread dough. I used just a standard bread recipe - 500g flour, sachet of fast yeast, 2 tsp sugar, 1.1/2 tsp salt, good glug of olive oil and 300ml of warm water.
Make the bread dough as you would normally, and leave covered to rise for 30mins or until doubled in size.
Knock the dough back and roll it out into a rectangle about 1cm thick
Then, it's time to fill your bread. I chose to spread mine with red pesto and fill with some chopped antipasto. I'd griddled off 4 bell peppers, 1 courgette and a rather enormous onion.
