- 10 slices whole wheat bread, or your favorite bread
- Preheat oven to 250 degrees F (120 degrees C).
- Using tongs, place bread slices directly on oven racks. Leave in oven until hard and golden brown, about 30 minutes; darker if you prefer. Remove and cool on wire rack.
- Crumble slices into a large bowl until reduced to fine crumbs, or place in bowl of food processor and process until fine.
