Yassa and Ceebu jen

Ceebu jen (or Thiéboudienne) is Senegal's national dish, which I have eaten on multiple occassions. It is always served family style at home, on a big dish with with lots of rice cooked in a tomato based sauce. Marinated fish and cooked vegetables top the rice, all of which is eaten with the hand forming balls of rice and eating them with the other items. 

Another popular food here in Dakar, served in houses and restaurants alike is Yassa. This describes an onion, lemon and mustard sauce that is served over chicen or fried fish. Also very good and versatile in it's application to nearly any type of food. In addition to the usual chicken, fish, and meat I've had Yassa on eggs and even pasta.
