Preheat the grill to medium. Add the blackened tomatillos and serrano to a small saute pan and briefly saute in a little olive oil on the grates of the grill.
Place the tomatillos, serrano, onion, garlic, cilantro, lime juice, and honey in a blender and blend until smooth. Place the tomatillo mixture in a large saute pan and place on the grates of the grill. Bring the mixture to a simmer, add the chicken, and heat through.
Place the tortillas on the grill, and grill for 20 seconds on each side. Spoon the chicken mixture into the tortillas and top with a few tablespoons of queso fresco. Fold the tortillas in half serve immediately.
