To assemble Calzone
Divide dough in 2-4 pieces or or reserve some remaining dough in the fridge until the next pizza day. Roll each piece out into large circle on a piece of baking paper. Sprinkle with a little grated cheese and arrange some red capsicum over.
Divide the ricotta and spread on top, and then add mushroom mixture. Repeat with grated cheese, and the remaining capsicum.
Roll other half of dough into a large circle and lay over the top of the pizza. Bring base dough up and over the top dough and pinch all the way around to seal edges.
Slide onto the pizza stone and cook for approximately 25-30 minutes until golden all over.
Slice into large wedges and serve immediately.
