Preheat the oven to 350F. Combine all the pastry ingredients in a large bowl until a dough has formed. This works best when doing it by hand.

Place the ball of dough between two sheets of parchment and roll out until the dough is around 0.5 cm thick, then lay your dough over a 10-inch tart dish and gently push into shape, trimming any excess with a knife.

Bake the dough blind (with ceramic baking beans or similar) for 10 minutes, then remove the parchment paper and baking beans and return the pastry to the oven for another 10 minutes.

Meanwhile, assemble your filling ingredients. Finely chop the onion, herbs, and green onions, and grate the Parmesan. Rough chop the bacon and prepare the broccoli.

Combine all the filling ingredients except the green onions and mix well. Pour into your pastry case.

Top the tart with the green onions and bake for 30-35 mins, or until the filling is firm to the touch.
