Heat oil in a large skillet over medium heat.
Add onion, peppers and garlic and saute for 2-3 minutes.
Add zucchini, corn, black beans and cook while stirring for a few more minutes.
Move veggie mixture to a side of the skillet and add chicken.
Sprinkle with cumin, chili powder, a pinch of sea salt and black pepper.
Cook until no longer pink in the inside and golden brown, about 5 -7 minutes.
Once the chicken is cooked through, stir well to combine.
Add the cherry tomatoes and sprinkle with cheese, then cover and cook on low heat for a couple of minutes until cheese is melty.
Top with cilantro and enjoy!
