In a large skillet, heat 2 tablespoons of avocado oil over medium-high heat.
Add 1 cup of sliced red onions to the skillet and sauté until they become translucent, about 3-4 minutes.
Next, add 1 ½ lbs of chopped boneless skinless chicken breasts to the skillet. Cook for about 5-7 minutes, stirring frequently until the chicken is no longer pink and is cooked through.
Toss in the chopped zucchini and red bell pepper. Sauté for another 5 minutes, or until the vegetables are tender but still have a nice crunch.
Sprinkle 1 tablespoon of chili powder, 2 teaspoons of garlic powder, and 1 teaspoon of sea salt over the skillet. Stir well to coat the chicken and vegetables with the spices, cooking for an additional 2 minutes.
Once everything is well combined and heated through, remove from heat. Serve your 30-Minute Mexican Chicken and Zucchini Skillet warm, and enjoy the burst of flavors!
