Your quest for the perfect veggie burger is over. Agrawal’s version, adapted from a recipe in Lukas Volger’s cookbook, Veggie Burgers Every Which Way, is absolutely delicious. Mashed rajma (curried kidney beans) or canned beans get an umami burst with the addition of grated Parmesan and a melty slice of sharp cheddar cheese. Eggs and toasted breadcrumbs bind the mixture together, ensuring it will hold together in the pan. And don’t skip the piles of toppings. They make this already wonderful burger even more special.
