I hate to tell you, but it's just homemade pizza crust, then you use a pizza cutter to create full-thickness blimp-pattern lines in it before baking.
1 cup warm water
1 1/3 T yeast
1/2 t sugar
1 t salt
3 cups flour
Add a little water while kneading (for 8 minutes by hand or mixer) until it has the right bread dough consistency.
Bake at 400F for 15 minutes (pull it out momentarily at 9 minutes to put the cheese on).
It sounds very ancient and traditional, doesn't it? Actually I think this is adapted from Aunt Pat's pizza dough recipe. There is a way to make it that takes 3 days while you wait for the yeast to naturally occur, but it tastes about the same, gets eaten in 10 minutes, and this year we are midwesterners, not middle-easterners.
Oh, this is the tip of a small iceberg of good food from over there. To make it really good, completely coat it with sesame seeds.
