Gather all ingredients.

Combine green onions, onion, chile pepper, soy sauce, vinegar, vegetable oil, brown sugar, thyme, cloves, nutmeg, and allspice in a food processor or blender; process for about 15 seconds.

Place the chicken in a medium bowl, and coat with the marinade. Cover and refrigerate for 4 to 6 hours, or overnight.

Preheat grill for high heat. Lightly oil grill grate. Cook chicken breasts on the prepared grill until no longer pink in the center and the juices run clear, about 8 to 10 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

Transfer chicken to a platter and serve with lime wedges.
