1Stir together water, yeast and sugar. Let stand 5 minutes. Meanwhile, place cereal in resealable food-storage plastic bag; seal bag and crush with rolling pin or meat mallet (or crush in food processor).
2In food processor, place crushed cereal, flour, cheese, black pepper, red pepper, lemon peel and garlic salt. Cover; process about 10 seconds or until blended. Add oil; cover and process 10 seconds longer. Add yeast mixture; cover and process, using quick on-and-off motions, until dough forms a ball. Let rest 5 minutes. Cover and process 10 seconds longer. Remove dough; cover and let rise 10 minutes.
3Heat oven to 325°F. Spray 2 cookie sheets with cooking spray. Divide dough into 16 equal pieces. On surface sprinkled with cornmeal, roll each part into thin rope about 14 inches long. Place on cookie sheets. Brush with egg white; sprinkle with additional ground black and red peppers if desired. Let stand 15 minutes.
4Bake 25 to 35 minutes or until golden brown and crisp. Cool on cooling rack.
