In a large bowl combine the first 4 ingredients and stir well. Slice the chicken breast lengthwise into 1/4 inch thick pieces (about five per breast). Skewer the chicken slices onto the bamboo sticks and place into a zip lock bag. Pour the marinade into the bag and place in  refrigerator for one hour (or overnight). Remove the chicken skewers from zip lock bag and discard the remaining marinade. Sprinkle the sesame seeds over the chicken and grill over a medium fire for four minutes per side (or until cooked through). Serve warm or at room temperature.
