Sarah Hoyt recommended the Fat Head pizza crust recipe to me, as low carb and yet tasty. I have to agree, this is the first pizza crust of the low carb variety I've run into that is actually as good as the wheat-based version.
One minor note: it's incredibly filling. I didn't have parchment paper, so I patted it out by hand on a silicone baking sheet into roughly a 9x11in crust. I loaded it up with toppings, hoping it'd be enough with a salad... and between Peter and myself, we had half a leftover pizza and leftover salad.
Definitely a keeper... and good enough for company! I loaded it up with straight tomato paste for the sauce, sauteed bell pepper & onion strips, chopped basil out of the garden, the last of the pepperoni in the fridge, and some sausage, then added a little oregano and plenty of mozzarella on top. The recipe called for 5 minutes more of baking, but I hit it with 30 seconds of broiling to give the cheese topping that proper touch of browning and faint blackening on the toppings that poked through.
