In a large skillet over medium heat, add the olive oil. Once hot, add the diced chicken and season with salt, pepper, cumin, smoked paprika, and chili powder. Cook for about 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Add the chopped onion and garlic to the skillet with the chicken. Sauté for another 2-3 minutes until the onion becomes translucent.
Stir in the sliced zucchini and diced red bell pepper. Cook for an additional 5-7 minutes, allowing the vegetables to soften but maintain some crispness.
Add the corn and black beans, stirring everything together. Cook for another 3-4 minutes, allowing the mixture to heat through.
Sprinkle the shredded cheddar cheese evenly over the chicken and vegetable mixture. Cover the skillet and let it sit for about 2-3 minutes until the cheese melts.
Remove from heat and sprinkle with fresh cilantro. Serve with lime wedges on the side for an extra zing.
