In a soup pot, heat 9 tbsps vegetable broth over medium-high heat, and then sauté the onion and garlic until softening.
Add the remaining vegetable broth, diced tomatoes, and tomato paste, and bring to a boil.
Add the quinoa and cook at a simmer for 15 minutes.
Add the kidney beans, pinto beans and chickpeas, then stir in the chili powder, black pepper, cumin and garlic powder. Continue cooking until all the ingredients are heated through, about 5 to 8 minutes.
Transfer to a bowl and enjoy!
