Heat olive oil in a large skillet over medium heat. Add diced red onion and garlic, sautéing for about 2-3 minutes until softened and fragrant.
Add the diced chicken breast to the skillet. Season with salt, pepper, chili powder, cumin, and smoked paprika. Cook for about 5-7 minutes, stirring occasionally, until the chicken is golden and cooked through.
Incorporate the diced red and green bell peppers into the skillet and cook for another 3 minutes until they start to soften.
Stir in the quinoa, chicken broth, black beans, and corn. Bring the mixture to a boil, then reduce the heat to low. Cover the skillet and let it simmer for 15-20 minutes, or until the quinoa is cooked and has absorbed the liquid.
Once the quinoa is fluffy and all ingredients are well combined, taste and adjust seasoning as necessary.
Remove from heat and let sit for 2 minutes. Garnish with fresh cilantro and serve with lime wedges on the side.
