Ingredients
1
3/4 lb beef tenderloin roast, trimmed
6
(1/4-inch-thick) rounds of red onion (cut from 1 large)
3
medium zucchini (1 lb), sliced 1/4 inch thick lengthwise
Special equipment: 6 (8-inch) bamboo skewers
Directions
1.
Soak skewers in water while marinating beef.
2.
Cut beef into 24 (1-inch) cubes. Stir together soy sauce, lime juice, salt, and cumin in a bowl and add beef, tossing to coat well. Marinate beef, covered, at room temperature 1 hour.
3.
Prepare grill for cooking.
4.
After beef has been marinating 45 minutes, lightly brush onion rounds with oil and season with salt and pepper. Grill onion on a well-oiled rack set 5 to 6 inches over glowing coals, carefully turning once with a metal spatula, until lightly charred and tender, 3 to 4 minutes on each side. Transfer to a platter and keep warm.
5.
Arrange zucchini on grill and grill until lightly charred and just tender, about 1 minute on each side. Transfer to platter and season with salt.
6.
Pat beef dry with paper towels and toss with remaining oil. (Discard marinade.) Thread 4 pieces beef onto each skewer and grill, turning occasionally, until charred, about 5 minutes total for medium-rare.
7.
Serve kebabs with onion and zucchini.
9.
Instead of the grill, you can cook the vegetables and beef in a hot well-seasoned ridged grill pan over moderately high heat.
