Siomay (also somai) (Chinese: 燒賣; Pe̍h-ōe-jī: sio-māi) is an Indonesian steamed fish dumpling with vegetables served in peanut sauce.

[1] It is traditionally made from pork but is frequently substituted with tenggiri (Spanish mackerel), as many Indonesians observe the halal dietary law.

Sometimes other types of seafood such as tuna, mackerel, and prawn or poultry such as chicken also can be used to make siomay.

[3] Other complements to siomay include steamed cabbage, potatoes, bitter gourd, boiled egg, and tofu.

[1] It can be found in street-side food stalls, travelling carts, bicycle vendors, and restaurants, and is considered a popular school meal for Indonesian students.
