Plant-based burger chef-guru Lukas Volger wrote Veggie Burgers Every Which Way and created Made by Lukas, all with the aim of making vegetarian food tasty and hearty (he’s also behind Vegetarian Entrees That Won’t Leave You Hungry). Now, he’s applying that same expertise to an of-the-moment healthy food trend: bowls., with smart, simple recipes that range from Fennel Pho to Summer Squash Dumplings and a Black Rice Burrito Bowl.
