1 1/4 lb boneless skinless chicken thighs
1/4 tsp kosher salt
1/4 tsp freshly ground black pepper
2 tbsp olive oil
16 oz salsa verde
12 corn tortillas
1 avocado, sliced
1/2 cup finely chopped red onion
1/2 cup fresh cilantro, chopped
2 oz cotija cheese, crumbled
Lime wedges, for serving
Sprinkle chicken with salt and pepper. Heat oil in a large pot or Dutch oven over medium until shimmering. Add chicken; cook until golden brown, about 3 minutes per side. Add salsa verde. Reduce heat to medium-low; cook, partially covered, stirring occasionally and flipping chicken halfway through, until a thermometer inserted in thickest part of a chicken thigh reads 165°F, 6 to 8 minutes. Remove from heat and let cool for 5 minutes.
Transfer chicken to a large bowl and shred with 2 forks. Return chicken to pot and toss with salsa verde until well coated.
Warm tortillas in microwave, over a gas flame on stove, or in a dry skillet. Top tortillas with chicken, avocado, onion, cilantro, and cheese. Serve with lime wedges, if desired.
