For the mushroom mince pizza topping:
For the base and extra toppings:
Preheat the oven to 220c/200c for fan oven. Prepare 4 pieces of baking parchment to fit a baking sheet.
Mix together all the ingredients for the topping and season with salt and pepper.
Divide the dough into 4 pieces. Stretch each one out into an oval shape, getting it as thin as you can. Place each base onto a piece of parchment.
Thinly spread the topping over each base.
Slice the remaining mushrooms. Sprinkle the pizzas with the sliced mushrooms, feta and pine nuts and a drizzle of oil.
Bake in the oven for 15 mins until crisp and golden. Sprinkle with parsley before serving.
