Spray a large skillet with cooking spray (I recommend
Pompeian Avocado Oil Spray, so good!). Head the skillet to medium-high heat; then add the diced chicken breast & chopped jalapeño. Season with taco seasoning (or mixture of cumin & chili powder) along with the garlic salt. Cook until the chicken is lightly browned & cooked through. Once cooked through, transfer the chicken to a separate dish; set aside.
