Boneless chicken breasts can replace chicken thighs, although cooking times will vary.
Avocado oil or another neutral high-heat cooking oil can replace vegetable oil.
If you don't have chipotle chili powder, use additional regular chili powder and a small amount of smoked paprika for a similar smoky character with less heat.
Serve the chicken with steamed rice, roasted potatoes, grilled vegetables, corn, coleslaw, or a crisp green salad.
