Preheat oven to 350 degrees F. Combine nutritional yeast, garlic powder, salt, ww flour, oat flour, cornmeal, baking powder, and turmeric in your food processor. Pulse until combined.

Add in olive oil and combine once more. While processor is running, dribble in water (just enough until a cohesive, crumbly mixture has formed). You don't want the dough to be too wet. Remove dough with your hands and mold into a ball.

On a lightly floured surface, roll out (using a rolling pin or long glass) into a rectangle with about 1/8 inch thickness. Slice into desired cracker shapes, using a toothpick or chopstick to make an indentation in the center of each.

Bake for 15-20 minutes, until golden and slightly puffy. The crackers will firm up more outside of the oven. Let cool completely and make sandwiches with 1 tsp peanut butter in between each cracker.
