Heat cooking oil over medium heat in a medium to large pot. Saute onions for 2 minutes, add chili, garlic, cumin, and coriander. Cook for 1-2 minutes more. Stir regularly.
Stir in tomatoes, sweet potato, carrots, uncooked quinoa, oregano, salt, pepper, and water. Stir well. Cover and cook for 10-15 minutes. Stir occasionally.
Tip: cook quinoa separately, according to the package, if you want to cook more for a lunch salad. Otherwise add uncooked quinoa straight to the pot when you add the tomatoes.
Add beans and cook for 5 minutes more.
If you cooked quinoa separately, add last minute. Stir well and serve.
Optional: top with cashew or sour cream
