Add the bulgur, beans, tomatoes, tomato paste, chili powder, smoked paprika, dried mustard, cumin, salt, and broth to the pot. Bring the mixture to a boil. Reduce the heat to low, cover, and simmer for 15 minutes, or until the bulgur (or quinoa) is cooked through. If adding vegetables, uncover the pot and add them after 10 minutes. Taste the chili and adjust salt as needed. Serve, with corn chips, avocado, chopped green onion tops, or any other toppings you enjoy!
