In a mixing bowl whisk the chickpea flour, water, two-thirds of the oil and salt together until smooth. Let the batter sit for 1 hour at room temperature.
About 10 minutes before the batter is done resting preheat the oven to 450ºF and place two cast-iron pans inside the warming oven.
Remove the pan from the oven and turn the broiler to high. Add the remaining oil to the pan and swirl to coat. Pour the batter into the pan and place it under the broiler for 5 to 7 minutes until the edges have browned and the top of the flatbread is firm. Remove from the oven.
Reduce the oven temperature to 350ºF. Remove the chickpea flatbread from the pan and transfer to a baking sheet. Top it with pizza/tomato sauce, spices and shredded cheese. Return to the oven and bake for 10 until the cheese is bubbly and browned.
Slice and serve immediately. Enjoy!
