Chopsticks and rice

You tilt the bowl towards your face and use the chopsticks to rake the food into your mouth.

Cheap, easy to make/find, a good choice for a developing civilization.

Chopsticks practice patience and show rank in society.

Chopsticks, funnily enough, were used as a replacement for knives in Confucian eras. Knives were equated with violence when eating, thus the "chop"sticks were born.
