Preheat the oven to 450 degrees F. Line 2 baking sheets with parchment paper
In a large bowl, combine both flours, sugar, salt, and pepper.
Add the olive oil and water, stirring until a shaggy dough forms.
Turn the dough onto your work surface. Use your hands to lightly knead it for a few minutes and gather it into a smooth ball.
Loosely drape the dough with a towel or plastic wrap. Let it rest for 10 minutes.
On a lightly floured work surface, roll out the dough into a rectangle that is about 1/16-inch thick. Use a pizza roller or fluted pastry cutter to cut the dough into 1-inch by 3-inch rectangles. (You can also use a sharp knife or a cookie cutter.) Gather the scraps, re-roll them and continue cutting the crackers.
Place the unbaked crackers on the prepared sheet pans. Brush with water and sprinkle with everything seasoning.
Bake for 12-14 minutes until golden brown. Cool on a wire rack.
