Preheat the oven to 325 degrees F. For the tart shell, combine the pork rinds, cheese and mix well.

Add the egg and mix until the dough is well combined and stiff (add more powdered pork rinds if needed). Press pie crust into a 9 inch pie dish. Cook the crust for 12 minutes, or until it starts to lightly brown.

To make the filling, place in a medium bowl, broth, Swiss cheese, butter and cream cheese. Stir well to combine. Stir in the ham, eggs, and salt. Pour mixture into pre-baked shell.

Place into the oven or air fryer and bake for 15 minutes. Reduce heat to 300 degrees F (150 degrees C), and bake an additional 30 minutes, or until a knife inserted 1 inch from edge comes out clean. You may have to cover the edges with foil to prevent over browning. Allow quiche to sit 10 minutes before cutting into wedges.
