Not a recipe (they're all at home), but our favorites are regional (Central Ohio). We buy the Donatos brand Gluten Free Take and Bake fresh pizzas locally (Central Ohio) and their frozen line called Sonoma Flatbread. They're pretty good, especially if baked on a stone.
If you're looking for a recipe, the one in the Gluten Free Gourmet for pizza crust is a pretty good starter recipe.
