Cauliflower Crust Pizza (It Really Is Delicious

This recipe is based on Starlene's: http://gapsdietjourney.com/2012/04/recipe-review-cauliflower-pizza-crust... . It's amazingly tasty! It's a bit of work, but every so often, for a treat, we have pizza for dinner (one of these pizzas serve two generously, so I double the recipe and rotate the pans in the oven during baking.

1 good-sized cauliflower, flowerettes pulsed--using S-blade in food processor--to make rice-sized grains.
1 tsp. oregano
1 whole egg
pinch of salt
about 1 cup highly-seasoned, homemade tomato sauce (it should be thick and not too runny)
Toppings: thinly sliced mushrooms, olives, onion, etc.
4-8 oz. delicious raw cheese (jack, or whichever hard cheese works for you), grated

Using a steamer basket set over simmering water, steam the cauliflower "rice" for about 6 minutes, until tender.

Meanwhile, line a "jellyroll pan" (sheet pan with a rim) with parchment paper, and butter the parchment. Preheat the oven to 350f.

Line a colander with a thin dishtowel. Carefully dump the steamed cauliflower (but not the steaming water) into the lined colander. Gather the edges of the cloth, when the cauliflower is cool enough to handle, and squeeze out any liquid.

In a large bowl, combine the cauliflower, oregano, salt, and egg. Mix well, and dump onto the parchment lined sheet pan.

Press the mixture into a flat crust shape (slightly rectangular works well), about 1/4" thick.

Bake for 40 minutes.

Carefully slide the pizza crust from the parchment paper onto a cooling rack. Allow to cool for up to 3 hours.

When you're ready to top the pizzas, gently put the crust back onto the parchment; spread the sauce evenly and thinly over the top, and put the toppings evenly and thinly over that.

Return to a preheated 400f oven for ten minutes or so, or until the sauce is quite hot and the toppings are cooked as much as you like. Sprinkle the cheese evenly on top, and return to the oven only until the cheese is slightly melted (30 seconds or so), if you want to preserve its raw-ness. (Otherwise, melt until goopy and perfect!)

Enjoy immediately!
