Start by adding oil to a large pot. I like to use my Dutch oven but any large pot works.
Then, add the onion and cook until translucent. Add garlic, stir, and cook for 30 seconds.
Add the red bell peppers to the pot and cook for 5-7 minutes or until softened.
Next, add beans, tomatoes, green chilies, sweet potatoes, corn, and vegetable broth to the pot, along with a variety of spices. Cover and let the chili simmer over medium-low.
Cook for 30 minutes, stirring occasionally, or until chili has thickened. Taste and add more salt and pepper if desired.
Serve immediately with toppings of your choice.
