Whisk together the minced chipotle peppers, adobo sauce, vegetable oil, lime juice, garlic powder, cumin, oregano, and salt in a bowl.
Add the chicken thighs to the marinade, toss to coat evenly, cover, and refrigerate for 30 minutes.
Heat a grill or grill pan over medium-high heat until very hot.
Grill the chicken for 5 to 6 minutes per side until charred and cooked to 165°F / 74°C at the thickest part.
Rest the chicken for 3 minutes, then chop into bite-size pieces.
Serve the chicken over rice, in bowls, tacos, or salads with your favorite toppings.
