In a medium bowl, toss the chicken, garlic, soy sauce and oil. Sprinkle the taco seasoning and mix well.
Airfry at 400 for 10-12 minutes OR cook in the oven on a foil/parchment lined rimmed sheet pan at 425 degrees for 20-25 minutes.
Meanwhile, in a large skillet, heat over medium-high. Add about 1 tbsp of avocado oil. Add the veggies and cook until tender with some char spots.
When the chicken is golden, cooked through and has some char spots, leet rest about 10 minutes. Chop and use in bowls, tacos, or quesadillas.
