Black Beans and Rice

I am listening to a book on tape called "Havanna Dreams." It has a lot
of Cuba's history in it as related to Fidel Castro. One section was
talking about this dish that was named in such a way that it sounded
like it had Racial Overtones. The black bean and rice dish was called
"Moros y Christianos" or something like that.

Has anyone ever heard of this or other foods that had reference to Race?
