Open all canned ingredients. Pour corn and beans into a strainer and rinse thoroughly. Set aside.
Heat a tablespoon of olive oil in a large pot. Peel and chop the sweet potato and onion. Add both to pot and saute for a few minutes until onions become translucent.
Add broth, all canned products, quinoa, and spices. Give everything a good stir, bring to a boil, then reduce heat to a low simmer. Continue to simmer 25 minutes to allow quinoa to cook and flavors to blend.
