Combine mashed avocado, cilantro, vinegar, half-n-half, sour cream, mayonnaise, onion powder, garlic, hot sauce, hot chili oil, and salt. Blend it well, cover and refrigerate while you prepare and marinate the chicken.
Place thawed chicken tenders in plastic bag with the McCormick Salt-free All Purpose Seasoning and black pepper.
Shake the bag to coat the tenders. Let sit at least 1/2 an hour on counter just until meat reaches room temperature.
Preheat olive oil in a medium non-stick skillet on medium heat.
Place the seasoned tenders in hot oil, cook for about 3 minutes, turn over, cook another 2 to 3 minutes.
Immediately remove from pan to serving plate.
Sprinkle with course ground salt, and top with avocado dressing. Serve immediately.
