Divide the pastry in two. 1/3 for the top and 2/3 for the base. Roll out pastry to fit a 30 x 20cm tart tin. Add filling and then the pastry top, trim any excess pastry and crimp edges with a fork. Cut a little cross in the centre to let out any steam. Decorate with any excess pastry if you wish.
Brush with egg and bake for 40 minutes. Allow to cool slightly and serve.
For the filling
While the pastry is resting, add oil to a frying pan and cook the onions over medium-low heat untl soft and only very lightly golden. Add garlic and prosucito and cook while stirring for a couple of minutes. Add to a large bowl.

Only a minute or so. Remove and refresh under cold water. Squeeze out the water well and add to the onion mixture.
Also add, ricotta, egg, parsley and season very well with salt and pepper.
Notes
Dont be too concerned about quantities for the filling. Add as much or as little as you like. Olive oil pastry recipe is from one of my favourite blogs www.italyonmymind.com.au
