Heat olive oil in a large deep skillet over medium heat.
Sauté diced onions for 4 minutes until translucent, then add minced garlic and cook for 60 seconds until fragrant.
Incorporate rinsed quinoa, black beans, corn, diced tomatoes with their juices, vegetable broth, chili powder, cumin, paprika, and salt into the skillet.
Stir the mixture thoroughly and increase heat to bring the liquid to a rolling boil.
Reduce heat to low, cover the skillet with a tight-fitting lid, and simmer for 18 to 20 minutes until the liquid is fully absorbed by the quinoa.
Remove the skillet from heat and immediately sprinkle the shredded cheese over the surface.
Cover the skillet for an additional 2 minutes to allow the residual heat to melt the cheese.
Garnish with chopped cilantro and serve immediately.
