Medium bell peppers (2 pcs): Chopped to bring sweetness and color to the dish.

Low sodium black beans (14 oz can): Drained and rinsed for protein and fiber boost.
Low sodium diced tomatoes (14 oz can): Added with juices to create a light sauce.
Store-bought or homemade taco seasoning (1 tsp): Brings classic Tex Mex spice notes.
Cumin (1 tbsp, divided): Earthy warmth that balances the fresh vegetables and chicken.
Salt (1 tsp): Enhances all the natural flavors in the dish.
Ground black pepper (to taste): Adds mild heat and depth.
Tex Mex or Colby Jack cheese (1 cup): Shredded to melt and create a creamy topping.
Chopped green onions (1/2 cup): Fresh herbal brightness as garnish.
Chopped cilantro (1/2 cup): Adds citrusy, fresh notes to finish.

Instructions

Preheat and Sauté Aromatics: Preheat a large 12-inch deep skillet over low to medium heat and swirl in oil to coat. Add the chopped onion, minced garlic, and diced bell peppers. Sauté for about 3 minutes, stirring occasionally to soften and release their sweet, savory flavors.
Cook the Chicken: Push the sautéed vegetables to one side of the skillet and add the chicken pieces. Sprinkle 1 teaspoon of cumin, salt, and black pepper over the chicken. Cook for approximately 5 minutes, stirring occasionally until the chicken is browned and nearly cooked through, locking in moisture and flavor.
Add Vegetables, Beans, and Seasoning: Incorporate corn, rinsed black beans, diced tomatoes along with their juices, diced zucchini, taco seasoning, and the remaining cumin. Stir everything together and cover the skillet. Let it cook over low to medium heat for 10 minutes, allowing flavors to meld and vegetables to soften without becoming mushy.
Top with Cheese and Garnish: Sprinkle shredded Tex Mex or Colby Jack cheese evenly over the mixture. Cover the skillet again and let the cheese melt for a few minutes. Once melted, remove the lid and garnish with chopped green onions and fresh cilantro to add color and fresh herbal notes.
Serve and Customize: Serve the dish hot, either on its own or paired with Instant Pot brown rice or quinoa for a well-rounded meal. For extra flavor, add sour cream, black olives, crushed tortilla chips, or use as a filling in low-carb wraps topped with sliced avocado for a nutritious twist.

You Must Know

If using large garden zucchini, dice into smaller cubes rather than quarters for even cooking.
