If using bamboo skewers, soak in water for at least 30 minutes. Prepare the grill for direct
cooking over medium heat (350° to 450°F).
In a medium bowl combine the marinade ingredients. Put the swordfish steaks in the bowl,
cover, and marinate at room temperature for 15 to 30 minutes while the grill preheats.
Thread the swordfish and tomatoes alternately on the skewers. Discard any remaining marinade.
Brush the cooking grates clean. Grill the kabobs over direct medium heat , with the lid closed as much as possible,
until the swordfish is opaque in the center but still juicy, 8 to 10 minutes, turning several times. Remove from the grill and serve right away.
