What is the name of Armenian food made with ground beef and bulgur rolled into meatballs eaten raw?

The Armenian food you are describing is called kufta.

It's not typically eaten raw, though. Kufta is usually cooked in a broth or sauce, or sometimes pan-fried. The raw version you are thinking of may be a specific type of kufta that is a variation on the traditional recipe, or it could be a misunderstanding.

While there are various types of Armenian kufta, all are generally made with ground meat, bulgur wheat, and spices, and are often served with a yogurt sauce or a garlic-based sauce.
