Today is all about the heart of the home: the kitchen! Melissa Joan Hart is here, and she's giving us a tour of the kitchen on the set of her new Netflix show, "No Good Nick." Plus, Tracy Pollan and her family are serving amped up veggie nachos — and we're going inside the coolest kitchens of our viewers from across the country. Then, meet Brussels Sprout, the adorable shopping dog. And Rachael's making a spring pasta with red pepper sauce!
