For the chicken wings: In a small bowl combine the Stubb's Green Chile Anytime Sauce with the garlic, brown sugar, lime zest and juice and whisk. Place the chicken wings in a zip-top plastic bag. Pour the marinade over the wings, seal the bag and let marinate for several hours.
Grill the wings: Heat the grill to a medium high heat, about 400° degrees, and arrange the wings on the grates so they don't fall through. Cook until wings are crispy and cooked through, turning once or twice. About 15-20 minutes. Watch for hot spots on the grill, since the marinade has brown sugar, it may have a tendency to flame.
Transfer wings to a platter and sprinkle with jalapeño slices, queso fresco, lime wedges and cilantro. Serve with dipping sauce.
