• 2 tbsp olive oil
• 1 tsp ground cumin
• 1 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper
• 8 small corn tortillas
• 1 medium, thinly sliced red onion
• 1/2 cup white vinegar
• 1 tbsp granulated sugar
• 1/2 cup water
• 1/4 cup chopped fresh cilantro
• for serving lime wedges

Instructions

1. Step 1: In a blender, combine 2 chipotle peppers, 2 tbsp adobo sauce, 2 tbsp olive oil, 1 tsp ground cumin, 1 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper; blend until smooth to create the marinade.
2. Step 2: Place 1 lb boneless skinless chicken thighs in a bowl and toss with the chipotle marinade, coating evenly. Cover and refrigerate for at least 1 hour or up to 4 hours.
3. Step 3: Meanwhile, prepare pickled onions: In a small saucepan, combine 1/2 cup white vinegar, 1/2 cup water, and 1 tbsp granulated sugar. Bring to a simmer over medium heat until sugar dissolves, about 2 minutes.

5. Step 5: Preheat a grill or grill pan over medium-high heat. Grill the marinated chicken thighs for 5-6 minutes per side until cooked through and lightly charred.
6. Step 6: Remove chicken from grill and let rest for 5 minutes, then slice into thin strips.
7. Step 7: Warm 8 small corn tortillas on the grill for 30 seconds each side until pliable and slightly charred.
8. Step 8: Assemble tacos by dividing sliced chicken among tortillas, topping with pickled red onions and 1/4 cup chopped fresh cilantro. Serve with lime wedges for squeezing over tacos.
