Directions

1. 1. Preheat the oven to 350°F.
2. 2. Combine the wheat bran, protein powder, and salt, stirring them together well. Stir in the water, making sure everything is wet, and let the mixture sit for about 5 minutes.
3. 3. Cover a cookie sheet with baking parchment and turn the dough out onto the parchment (the dough will be very soft). Using the back of a spoon, pat and smooth this out into a thin, even, unbroken sheet.
4. 4. Bake for 10 minutes, and use a pizza cutter or a knife with a thin, sharp blade to score the sheet of dough into crackers. Put the sheet back in the oven, and bake for another 20 minutes.
5. 5. Turn the oven to its lowest temperature, and let the crackers sit in the warm oven for at least 3 hours, until they're good and dry and crisp.
6. 6. Break apart, and store in an air tight container.
