Step 1

Trim the ends off of the zucchini, and then grate, using the large holes on a grater. Immediately transfer to a large bowl (so as not to lose any of the water from the zucchini). You should have about 3 cups of zucchini.

Step 2

Add the olive oil and salt to the zucchini, stirring to combine. Add the chickpea flour and 3 tablespoons of the water, stirring until blended. Add a little bit or all of the remaining water until mixture is a thick batter. Stir in the baking soda.

Step 3

Heat a cast iron skillet over medium heat. Lightly grease or spray (with nonstick cooking spray) the skillet.

Step 4

Add about 1/3 cup of batter to the center of the pan, and, working quickly, use the back of a metal spoon to spread the batter into a 6- to 7-inch circle. Turn up the heat to medium high and cook about 2 to 3 minutes. until a metal spatula slides under the flatbread easily (bottom side should be browned in spots).Flip over and cook to 2 minutes longer until browned on other side.

Step 5

Turn flatbread out onto a cooling rack and reduce heat to medium. Repeat with remaining batter,
