This combination Grilled Beef and Lamb Kebabs, known as Kefta, has chopped onion, garlic, parsley, cilantro, mint, and coriander mixed in for starters and toasted fennel and cumin all topped with a tahini yogurt drizzle. This needs to chill in the refrigerator for 1 hour minimum prior to grilling.
Toast fennel and cumin seeds in a small dry sauté pan, over medium-high heat, shaking pan often until fragrant, about 1 minute. Let cool and grind in a spice grinder.
In a food processor place the onion, garlic, parsley, cilantro, mint, and coriander and process until very finely chopped, scraping down sides of bowl.
Place in a fine mesh sieve and allow to drain excess liquid. Press with fingers or with back of spoon to extract.
Transfer mixture to a large bowl and add lamb, beef and toasted ground spices. Season with kosher salt and mix by hands until evenly combined. Chill mixture at least 1 hour.
Prepare grill at 450°. Clean and lightly oil grill grates.
Divide meat mixture into 8 portions and form each portion into a 5”-long sausage shape. Insert a metal skewer lengthwise through each portion.
Drizzle with olive oil and grill, turning occasionally, until just cooked through, 8–10 minutes total.
In a small bowl whisk together the yogurt, lemon juice and tahini. Season with kosher salt to taste and drizzle over kefta.
