01 - In a large bowl, whisk together minced chipotle peppers, adobo sauce, olive oil, minced garlic, lime juice, ground cumin, smoked paprika, dried oregano, salt, and black pepper.
02 - Add chicken thighs to the marinade, ensuring they are well-coated. Cover the bowl and refrigerate for a minimum of 30 minutes, or up to 2 hours for a more intense flavor profile.
03 - Preheat your grill or grill pan to medium-high heat.
04 - Remove chicken from the marinade, allowing any excess to drip off. Grill the chicken for 5 to 6 minutes per side, or until it is thoroughly cooked and exhibits light char marks.
05 - Transfer the grilled chicken to a plate. Tent loosely with foil and allow it to rest for 5 minutes. Once rested, slice the chicken into thin strips.
06 - Warm the corn tortillas on the grill or in a dry skillet for approximately 30 seconds per side until pliable.
07 - Assemble each taco by layering the sliced chicken, shredded red cabbage, diced red onion, chopped cilantro, sliced avocado, and crumbled queso fresco onto a warm tortilla.
08 - Serve the tacos immediately with lime wedges on the side.
