Kibbe (Syria) or kubba (Iraq) is a genre of pie or dumpling made with meat and cereal. The most common are made with ground meat (typically lamb) and burghul, worked together like a dough, then stuffed with minced meat that has been fried with onion, aromatics, and, sometimes, pine nuts or almonds and raisins. This can either be in the form of individual small dumplings (usually shaped like a torpedo), or in slices like a cake, baked on an oven tray with the stuffing placed between two layers of the dough. In the form of small dumplings, this can also be cooked in a sauce with vegetables. One striking variation is a kibbe niyye, raw kibbe, made by pounding lean meat and burghul together with seasoning, which is then served as small dumplings, sometimes with dips of lemon juice and chili sauce. In Anatolia this genre is known as kofte, in common with other ground meat rissoles: the stuffed version is called icli kofte, and the raw one is cig kofte. In Iraq and Iran, there are versions of this dumpling made with rice instead of burghul.

I have no idea if this has any relation to your surname at all!
