Prepare the Bulgur:
Place the bulgur wheat in a large bowl. Pour boiling water over the bulgur and let it soak until the water is absorbed and the bulgur is tender, about 20-30 minutes. Drain any excess water.

Make the Kibe Mixture:
To the soaked bulgur, add the ground beef, chopped onion, minced garlic, cumin, cinnamon, allspice, black pepper, salt, chopped mint, and parsley. Mix well until the ingredients are thoroughly combined. It helps to knead the mixture with your hands.

Prepare the Stuffing (if using):
In a skillet, cook the additional ground beef with chopped onion until the meat is browned. Add the pine nuts, cinnamon, salt, and pepper. Cook for a few more minutes until well combined. Set aside to cool.

Shape the Kibe:
Take a small portion of the kibe mixture and flatten it in the palm of your hand. Place a spoonful of the stuffing in the center (if using). Close the mixture around the stuffing and shape it into an oval or football shape. Repeat with the remaining mixture.

Fry the Kibe:
Heat oil in a deep fryer or a large, deep skillet to 350°F (175°C). Fry the kibe in batches, being careful not to overcrowd the pan. Cook until they are golden and crispy, about 5-7 minutes. Remove with a slotted spoon and drain on paper towels.

Serve:
Serve the kibe hot with lemon wedges, tahini sauce, or plain yogurt.
