In a bowl, mix olive oil, adobo sauce, minced garlic, chili powder, cumin, oregano, salt, and black pepper.
Coat the chicken evenly in the marinade and let it rest for at least 30 minutes (or overnight for deeper flavor).
Preheat a skillet or grill pan over medium-high heat. Lightly grease with oil.
Cook the chicken for about 6-7 minutes per side until golden brown and cooked through.
Let the chicken rest for 5 minutes before slicing to keep it juicy.
Slice or shred and serve in burritos, bowls, salads, or tacos.
