There was quite a bit of prep. It took about 20 minutes to prepare the vegetables. While John did that I cut the chicken down to bite size pieces for the Sweet and Sour Chicken and started it in the oven using a baking method. That worked out well as it finished just as the Vegetable Stir Fry finished. Even though there was a lot of vegetable prep we learned a few new techniques that we will be posting more about later, including videos. one method was an oblique cut. the other was a diamond cut.
