Light a medium-hot fire or preheat the broiler. Cut the chicken breasts
lengthwise into 3/4" wide strips. Thread the chicken strips onto 12 metal
or soaked bamboo skewers. Mince the garlic. In a small bowl, combine the
garlic, oil, cilantro and cumin. Brush some of the garlic oil over the
chicken strips. Grill or broil 3 to 4" from the heat for 4 minutes. Baste
the chicken with any remaining marinade, turn the skewers over and cook
until the chicken is nicely browned on the outside and white to the center,
3 to 4 minutes longer.
