Brooke has been a valuable Sous Chef and has graduated to a straight kitchen knife for prep (think non serrated steak knife).  Alex has now advanced to Station Chef and is using a butter knife to prep instead of the kids knife.  After Brooke did 1.5 bell peppers diced (I slice them into the strips to make it easier for the kids to dice), Alex was adamant about finishing the last half.  We even had to stop the cooking process to allow him the time to finish, but he did a great job!
