Grind the bulgur in a food processor.

Add the beef and onions to the bulgur and grind together.

For the filling: Sauté the beef and beef fat, then let cool. Add pine nuts or walnuts.

Shape the bulgur mixture into balls, then flatten into circles.

Place the filling on one circle, cover with another circle, press the edges firmly, and shape into a disk.

Grill over charcoal.

Enjoy!
