Start by seasoning your chicken breasts. In a small bowl, combine paprika, cumin, oregano, garlic powder, salt, onion powder, pepper, and chili powder. Rub this spice mixture all over the chicken breasts for an even coating.
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Once hot, add the seasoned chicken breasts and sear for about 5-6 minutes on each side, or until they are golden brown. Remove the chicken from the skillet and set aside.
In the same skillet, add the remaining tablespoon of olive oil. Add the chopped yellow onion and sauté for about 2-3 minutes until translucent. Then, stir in the minced garlic and cook for an additional minute until fragrant.
Add the drained corn, black beans, and fire-roasted tomatoes to the skillet. Stir well to combine and let everything simmer for about 5 minutes to allow the flavors to meld.
Nestle the seared chicken breasts back into the skillet with the vegetable mixture. Drizzle with lime juice and cover the skillet. Allow it to cook for another 10-15 minutes, or until the chicken is fully cooked and reaches an internal temperature of 165°F.
Once the chicken is cooked through, sprinkle the shredded Mexican blend cheese over the top. Cover the skillet again and let it sit for a few minutes until the cheese is melted and bubbly.
Remove from heat and sprinkle with fresh cilantro before serving. Enjoy your delicious Cowboy Chicken!
