Quinoa: In a small saucepan with a tight-fitting lid, set the broth to boil over high heat. Once it's boiling, stir in the quinoa, place the lid on, lower the heat to medium-low and let it cook for 15 minutes. After times up, turn off the heat, but leave the lid on for another 5 minutes. Then fluff the quinoa with a fork and set it aside.
Chili: In a large pot, heat the oil over medium heat. Once it's hot, add the onion and pepper with a pinch of salt. Cook until they've softened up a bit, about 5 minutes, then stir in the garlic and cook for another minute or so more, until fragrant. Then stir in the broth, canned tomatoes, tomato sauce and seasonings. Increase the heat to medium-high.
Once it starts to come to a low boil, add in the beans and sweet potatoes. Let this simmer until the sweet potatoes are tender, which will depend on how big you diced them. Once they are tender, remove the pot from the heat and stir in the cooked quinoa and the corn. Serve with whatever toppings sound good.
