Preheat the oven to 325°F (170°C). Combine all the ingredients, except the water, in a bowl and then slowly add the water, bit by bit, until the dough begins to stick to itself.
Lay a sheet of parchment paper on a baking sheet, place the dough on top, and use a rolling pin to flatten it out. Using a knife, score the dough into small rectangles.
Place the baking sheet in the oven and bake for 45 minutes.
Serve with hummus or another savory spread.
