Warm the pan: Heat olive oil in a large, deep skillet over medium heat.
Sauté aromatics: Add the onion and bell pepper. Cook, stirring occasionally, until softened and lightly golden, about 5–6 minutes.
Add garlic and cook 30 seconds until fragrant.
Toast the quinoa: Stir in the rinsed quinoa and let it toast for 1 minute. This boosts flavor and helps keep the grains fluffy.
Season well: Add smoked paprika, chili powder, cumin, oregano, chipotle or cayenne (if using), salt, and pepper. Stir to coat everything evenly.
Add liquids and veggies: Pour in the diced tomatoes with their juices and the vegetable broth.
Stir in the black beans and corn.
Simmer: Bring to a gentle boil, then reduce heat to low. Cover and simmer for 18–20 minutes, or until the quinoa is tender and most of the liquid is absorbed.
Rest and finish: Turn off heat and let the skillet sit, covered, for 5 minutes. Uncover, fluff with a fork, and stir in lime juice and cilantro.
Taste and adjust: Add more salt, lime, or heat as needed.
If you like it saucier, splash in a little extra broth or a drizzle of olive oil.
Serve: Spoon into bowls and add your favorite toppings. Enjoy hot.
