1. In a saucepan, bring the vegetable broth to a boil. Add the quinoa, reduce heat to low, cover, and simmer for about 15 minutes, or until the quinoa is cooked and the liquid is absorbed.
2. While the quinoa is cooking, heat the olive oil in a large skillet over medium heat. Add the onion and garlic, and sauté until softened, about 5 minutes.
3. Add the bell peppers, corn, and black beans to the skillet. Cook for another 5-7 minutes, until the vegetables are tender.
4. Stir in the cooked quinoa, cumin, paprika, salt, and pepper. Mix well to combine.
5. Transfer the mixture to a baking dish and bake at 350°F (175°C) for 10-15 minutes, until heated through.
6. Serve hot and enjoy!
