Packed full of lots of healthy ingredients, these oven-baked sweet potato burgers are truly inspired by southern cookingthey're made from sweet potatoes, quinoa, maple syrup, pecans and kale and absolutely no meat, eggs or dairy. This is a good one to bookmark if you need an idea to use up some leftover cooked or mashed sweet potatoes, or even if you have leftover cooked quinoa on hand. This recipe is vegetarian, and, as long as you use a vegan margarine or vegan butter substitute, they are vegan as well. All of the ingredients are gluten-free, but obviously, if you are planning to serve them on hamburger buns, you'll need to find some which are gluten-free if you're cooking for anyone with wheat and gluten sensitivities. These award-winning southern-inspired vegetarian and vegan sweet potato burgers made with quinoa were developed by tolerant vegan blogger nikki haney and courtesy of the north carolina sweet potato commission.
