Place the olive oil, chopped onions, sweet potatoes, beans, broth, quinoa, corn, and spices in a slow cooker.
Cook on high for 4 hours, or low for 7-8 hours.
After the cooking time, combine the cornstarch and water in a small container with a lid and shake well, then add to the chili. Stir well. Place the lid on and let it cook for 15 more minutes to thicken.
Serve with toppings of your choice.
Notes
You can use white or red quinoa.Feel free to use whatever vegetables you wish! If sweet potatoes don't work for you, use any root vegetable.If you don't want to make this in the slow cooker, you can make it on the stovetop. Bring it to a boil, and then cook on medium heat until the quinoa is cooked and the potatoes are tender.
