1.Cut corn crossways into eight pieces. Steam or microwave corn and eggplant, separately, until tender; drain.
2.Make spicy tomato marinade. Combine ingredients in large bowl.
3.Thread vegetables onto eight bamboo skewers; coat each kebab with spicy tomato marinade.
4.Spray barbecue grill plate with cooking-oil spray for 2 seconds. Cook kebabs, turning occasionally and brushing with remaining marinade, until vegetables are tender.
Soak bamboo skewers in cold water for at least 30 minutes before using to prevent skewers burning during cooking. The kebabs go well with a green salad.
