Preheat your oven to 400F. Line a baking sheet with parchment paper. Set aside.
In a large mixing bowl, toss in all dry ingredients. Combine. Pour in room-temperature water and mix until a dough forms. If the dough is too dry, add more water. It should be sticky.
Spread the dough onto your parchment paper and flatten. The thinner you flatten, the crispier the crackers will be.
Cut the flattened dough into squares (about 1-inch a part). You should end up with approximately 3-dozen crackers!
Bake for approximately 25 minutes (or until the edges are browned). Let cool, then break into squares.
Store the crackers in a container in a cool, dry place for up to two weeks.
