You probably have found it by now, but I came across your message as I was searching for the same recipe. I made it this summer but misplaced the recipe. I found it online through my public library. Here it is:

INDIAN-STYLE BEEF KEBABS WITH CILANTRO SAUCE
Makes 4 servings

1 bunch fresh cilantro (about 2 cups cilantro leaves)
1 small onion, peeled
2 cloves garlic, peeled
1 small green chili pepper, trimmed and halved, with seeds
1 (2-inch) piece fresh ginger, peeled
1 1/4 teaspoons kosher salt
4 tablespoons vegetable oil
3 tablespoons fresh lime juice
1/2 teaspoon curry powder
1 1/2-pound rib-eye steak, cut into 24 one-inch chunks
1 medium red onion, peeled
1 cup mango chutney
4 pieces naan bread (optional)

Place the cilantro, small onion, garlic, chili, ginger, and salt with 3 tablespoons of the oil in a food processor fitted with a metal blade. Process until a paste is formed. Transfer to a large bowl.

Put 2 tablespoons of the paste in a small bowl and stir in the lime juice to make the cilantro sauce. Cover and set aside.

Stir the curry powder into the rest of the paste. Add the steak and coat well. Cover and marinate at room temperature for 20 minutes.

Cut the red onion into 6 wedges and separate each wedge into 2 layers. Thread the beef and onion chunks onto eight 9-inch skewers.

Brush a grill pan with the remaining oil. Preheat grill pan, then grill the kebabs for 8 to 10 minutes, turning the skewers every 2 minutes.

Serve with the cilantro sauce, chutney, and naan, if desired.

TIP
You can use a grill or a grill pan for this recipe. If you're using bamboo skewers for these kebabs, soak them in water for 10 minutes before you thread the meat onto them.
