Preheat oven to 450°.
Cut each biscuit in half, and roll each half into a pencil-thin stick. Combine cereal and seeds in a shallow pan, stirring well. Brush biscuit sticks with egg white; roll in cereal mixture. Place breadsticks 2 inches apart on a large baking sheet coated with cooking spray, and sprinkle with salt.
Bake at 450° for 8 to 10 minutes or until lightly browned.
