Begin by finely chopping the yellow onion and fresh parsley using a food processor. Pulse until they achieve a fine consistency; set aside.

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

Mold the beef mixture around soaked wooden skewers into kebabs about an inch thick.

Preheat your grill to medium-high heat. Brush the grill grates with oil and place the skewers on the grill. Cook each side for about 4 minutes.

Remove the kebabs from the skewers and serve immediately with pita or dips.
