Preheat oven to 375
Line a baking sheet with parchment paper or use a Silpat (silicon mat). If using a Silpat, rub about 1/4 tbs oil on top of the mat to avoid sticking.
Put garbanzo flour into a mixing bowl and add the water to it, mixing with a whisk until well-blended and smooth.
Stir in garlic, basil, oregano, salt and pepper and pour onto the prepared baking sheet, spreading mixture to cover about 9X12 as evenly as possible.
Bake for 15 minutes, monitoring after 10 minutes. You want to see the flatbread start to crack a little, then remove from the oven.
Allow to cool, remove from pan onto flat wooden board and top with hummus and other toppings.
