The short crust pastry should be rolled out and layered in a greased pie pan. To make the filling, drain a can of tuna and put it in a bowl.
Add a pinch of milk, a handful of cheese, and a sprinkle of salt, pepper, and chilli flakes. Mix well. Add one egg.
For the top layer, save some cheese. Over the short crust pastry, spread this filling evenly.
Bake in the HYSapientia Air Fryer Oven at 190 degrees for 20 minutes.
