The Nigerian street food of thin-sliced, spiced meat grilled on skewers is suya.
Suya is a smoke-grilled Hausa food traditionally made with thin slices of beef, though lamb, goat, ram, chicken, organ meats, and sometimes seafood are also used. The meat is coated with yaji, a hot spice mixture that commonly includes chili or cayenne pepper, ginger, onion, salt, and ground peanut cake known as kuli-kuli.
Vendors thread the seasoned meat onto wooden skewers, oil it, and grill it over hot coals. The cooked meat is often removed from the skewers, cut into bite-size pieces, and served with extra yaji, onions, and tomatoes. It is especially popular as an evening snack and roadside food.
Suya is also called tsire in Hausa contexts. Kilishi is related but is the dried version, while balangu is another grilled-meat preparation. Those names explain why they can appear in the same food discussions, but the thin, spice-coated skewers in this question identify suya.
