First, start by preparing and cooking the caramelised onions and the flatbread dough if you're going to cook it from raw.
On top of the flatbread, layer the sliced bambinella pears and the gorgonzola cheese. Top it all with the caramelised onions.
If using a ready made flatbread bake for about 10 minutes until all the toppings are cooked and the cheese is melted. If you're cooking the flatbread from raw, the cooking time will be of about 15-20 minutes.
Once the flatbread is done and still hot, drizzle some honey on top and sprinkle several walnuts. Serve immediately.
