This is one of my favorite veggie burgers. It has everything I want: hearty chickpeas, fortifying spinach, a hint of nutty toasted cumin seeds, and final finish of fresh lemon. It's also very easy! As with most burgers in this book, be sure to reserve a portion of the beans and mash them by hand, rather than blitzing all of them in the food processor, as this gives the burger texture. I like to serve them accompanied by traditional burger fixings: lettuce, tomato, and mustard.
