- 4 slices whole-wheat sandwich bread (about 1 ounce each)
- Preheat the oven to 350°F.
- Place the bread in a food processor and process until fine crumbs form, 25 to 30 seconds. Place the crumbs on a baking sheet, spreading them evenly. Bake until golden brown, about 12 minutes. Store the bread crumbs in an airtight container for up to 2 weeks.
