Quinoa Chipotle Burger. If you are craving a burger, and want to try something that is new and completely fulfilling, you must give quinoa burgers a shot. The quinoa, beans, chia and flax seed pack an abundance of protein and fiber, as well as other nutrients. The chipotle seasoning and sauce give the burger a tangy hot and spicy flavor that will make you forget that it is so healthy. To keep it gluten free, we added grilled portobello mushrooms for the bun, and built our burger with avocado and carmelized onions. Yum, is all I can say, but judge for yourself.
