In a glass container with a lid, or Ziploc bag place chicken, 1 Tablespoon of the oil, minced garlic, taco seasoning, a pinch of sea salt and pepper.
Stir to combine and coat chicken well, and allow to marinate for a minimum of 30 minutes, up to 6 hours refrigerated.
Heat the remaining tablespoon of oil in a large skillet over medium-high heat.
Add in chicken pieces and stir until cooked through and golden brown, about 6-8 minutes.
Place all of the avocado sauce ingredients in a food processor or blender and pulse until creamy.
Layer lettuce wraps with chicken, and top with tomatoes, corn, and green onions, as shown.
Drizzle with creamy avocado sauce and enjoy!
