Heat olive oil in a large pot over medium heat. Add the chopped onion and bell pepper. Sauté for about 5 minutes or until they begin to soften.
Add the minced garlic and sauté for an additional minute until fragrant.
Stir in the rinsed quinoa, black beans, diced tomatoes (with juices), and vegetable broth.
Add the chili powder, cumin, smoked paprika, lime juice, salt, and pepper. Stir to combine all ingredients well.
Bring the chili to a boil, then lower the heat to a simmer. Cover and let it cook for about 20-25 minutes, or until the quinoa is cooked, and the chili has thickened.
Taste and adjust the seasoning, adding more salt, pepper, or spices as desired.
Serve the chili hot, garnished with fresh cilantro and avocado slices, if using.
Notes
Adjust seasoning to taste; avocado slices are optional for topping.
