Finger food
Finger food is food meant to be eaten directly using the hands, in contrast to food eaten with a knife and fork, chopsticks, or other utensils. In some cultures, food is almost always eaten with the hands; for example, Ethiopian cuisine is eaten by rolling various dishes up in injera bread. In the South Asian subcontinent, food is traditionally always eaten with hands. Foods considered street foods are frequently, though not exclusively, finger foods.
