Looking for a recipe for 'Suyya' - Nigerian Beef BBQ

Hi,

​

I grew up for the first 5 years of my life in Lagos in Nigeria. My favorite food there was 'Suuya' or 'suyya'. It was a spiced barbecued stick of beef.

​

I am looking for a recipe to make this from scratch.

​

Anyone know?

​

thanks!

bon appetit
