Made it today and it turned out excellent, much better than I expected. I was expecting the crust to be eggy but it wasn't. I can't wait until my son comes home to try it, he's the real critic.

I made two alterations:
I added 2 1/2 Tbs almond flour to the egg mixture; and I crumbled about 20 pepperoni chips at the bottom of the dish before pouring egg mixture.

I had a very firm crust which can be picked up with your hand. Delicious!
