Portabello Pizzas

I like this dinner because it's yummy like pizza, but there's no pesky carby-crust. It's mushrooms! Not bread!!
I cook the mushrooms in a pan for a few minutes on each side. When it sweats out a little bit, I put the sauce and then the cheese, and put it in the oven for a few more minutes, usually at 300.
I've done it with pepperonis for MB, and you could really top it with whatever pizza toppings you might like.
Mmmm, pizza.....
