Here is an example of a West African sweet potato dish called Yabeh.
Yabeh is a West African dish made with cassava, sweet potatoes or yams in a spicy tomato broth.
Sweet potato in a spicy tomato broth may be foreign to some AA palettes.
In Brazil they have Moqueca.
Which is a fish and sweet potato stew including tomato, peppers, coconut milk, and cilantro.
Again, same West African roots but different cultural variation.
Jamaican side dishes, or at least those served in American restaurants are a 1-1 parallel with Soul Food.
