In a dutch oven add the olive oil on medium heat. Once warm add the diced onion, diced bell pepper and minced garlic. Cook for around 3-4 minutes.
Once the onion, green pepper and garlic have cooked, add the diced green chilies. Stir until combined.
Add the spices (chili powder, cumin, oregano, smoked paprika, and hot pepper flakes) to the pot. Cook for 2 minutes.
Pour the diced fire roasted tomatoes, tomato sauce, and vegetable broth to the pot. Bring the ingredients to a boil and cook for 3-5 minutes. Next add the black beans, kidney beans, corn, red wine vinegar and quinoa. Cook for another 20 minutes on low until quinoa is cooked.
Once the quinoa has cooked, I transfer the chili to a crock-pot to keep warm and for easy transport. Serve the chili with shredded cheddar cheese, avocado slices, fresh cilantro on top and cornbread on the side.
