Cook quinoa according to package instructions.
When the quinoa is almost done, heat olive oil on medium heat in a large saucepan or dutch oven.
When the oil is shimmering, add onion and garlic. Saute onion and garlic for 1-2 minutes, stirring frequently. Add a little salt here.
Then, add the spinach leaves and cook for another minute, stirring frequently, until spinach is completely wilted.
Finally, add in diced tomatoes, vegetable broth, spices, cooked quinoa, and white kidney beans. Add some fresh ground pepper here too. Stir and cover.
Simmer for about 10 minutes on low-medium heat.
Taste before serving. Add salt and pepper to taste. Serve hot.
