Ingredients

• 1/4 cup olive oil
• 1 teaspoon ground cumin
• 1 teaspoon ground black pepper
• 3/4 teaspoon salt

• 1 3 1/2-pound sirloin half leg of lamb, bone removed, fat trimmed, meat cut into 1 1/4- to 1 1/2-inch pieces
• 6 12-inch metal skewers

Instructions

1. Whisk oil, cumin, pepper, salt and cinnamon in 13x9x2-inch glass baking dish. Add lamb to dish and toss to coat well with oil mixture. Let marinate at room temperature 1 hour or refrigerate 1 1/2 to 4 hours, tossing occasionally.
