1 small eggplant (about 12 oz.), cut into 1-inch cubes
1 red bell pepper, stemmed, seeded, cut into 1-inch pieces
1 yellow bell pepper, stemmed, seeded, cut into 1-inch pieces
1/2 pint cherry tomatoes
Directions
Make sauce: Stir yogurt, sour cream, and lime juice in a bowl until blended. Add garlic, cumin, and parsley; season with salt and pepper. Serve at room temperature or cover and chill.
Make kebabs: Prepare a charcoal fire and let burn to a gray ash. Toss lamb with cumin, salt, pepper, and oil.
Thread lamb onto 8 metal skewers, dividing evenly and alternating with eggplant, peppers, and tomatoes.
Brush kebabs with oil; season with salt and pepper.
Set grill 6 inches from heat. Grill, turning, until lamb is browned and firm, 12 to 15 minutes; serve warm.
