Begin by placing the quartered medium yellow onion and fresh parsley in a food processor. Pulse until finely chopped.

In a large mixing bowl, combine the lean ground beef with the finely-chopped onion-parsley mixture. Sprinkle in the salt, black pepper, seven spice blend, and cayenne pepper. Mix thoroughly.

With wet hands, mold the spiced meat mixture around soaked skewers into approximately 1 to 1.5-inch thick cylinders.

Preheat your gas or charcoal grill to medium-high heat, around 400°F to 450°F. Lightly brush the grill grates with oil.

Place the shaped kafta kebabs on the hot grill, leaving space between each one. Grill for about 4 minutes on one side, then flip them over and grill for another 4 minutes.

Once grilled, let the kafta kebabs rest for a couple of minutes before serving hot on a platter with fresh pita, hummus, or salad.
