This week The Kitchen has a special visitor, as Martha Stewart stops by to share her recipe for a Chocolate Chip Cookie Icebox Cake and gets inducted into the Kitchen's Cookbook Club. Jeff shares his family Blueberry Pancake recipe, Marcela makes Spicy Oregano Burgers for dinner and then shows how to turn them into Mini Meatball Pita Sandwiches for lunch. Plus, we have great ideas to sneak nutrition into your kids' desserts. And once again, we help you decide which kitchen tools are worth having in this week's Tool Takedown.
