Visit Palm Beach, Florida, where Dr. John Zahina-Ramos of Just One Backyard shows how to plant sweet potatoes in a wheelbarrow and then how to make a wall garden. Then visit Jojo Milano, who left the urban life of Miami to start a farm in rural Palm Beach County where she raises purebred Nubian and Lamancha goats and makes cheese from their milk. Next, head to the water to see how Eric Finn dives for the invasive lionfish and spiny lobster. Finish up in the kitchen of Chef Clay Conley, who serves up lionfish, escabeche-style.
