Heat a large Dutch oven over medium/high heat. Add olive oil. When the olive oil is fragrant, add the white onion and 1/8 teaspoon of salt to the oil. Toss and sauté for about 2 minutes. Add the garlic and cook for an additional minute.
Add the poblano pepper, green pepper, and quinoa to the Dutch oven. Mix well. Toast the quinoa for 3-4 minutes (stirring continuously) until it begins to brown.
Add the black beans, hominy, diced tomatoes, tomato sauce, chili powder, cumin powder, onion powder, paprika, pepper, and 4 cups of broth to the Dutch oven. Stir everything together and bring to a boil.
Once boiling, reduce the heat to low and and add the cinnamon sticks. Cover the Dutch oven and let the chili simmer for 10-15 minutes or until the quinoa is cooked.
The quinoa will have expanded during the cook time so when the quinoa is completely cooked, stir in the remaining 1 cup of broth.
Remove the cinnamon sticks and enjoy the chili topped with fresh cilantro and your favorite chili toppings such as sliced avocado, Greek yogurt/sour cream, etc.
