Preheat oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper or a silicone baking mat.
Mix all ingredients in a large bowl until well combined.
Knead dough into ball and roll onto the parchment paper or silicone baking mat 1/4 inch thick and take a straight edge and cut the dough horizontally and then vertically to make a grid (I used a pizza cutter).
Place on baking sheet and bake for 10 to 15 minutes.
Break into pieces and refrigerate.
