Do you season those avocados then? Like with salt, vinegar and oil?
If so, it's pretty similar to a typical Brazilian meal. Rice, beans, steak with onions, side salad (though in Brazil it's more likely to be lettuce, tomatoes and onions) is what I used to eat in Brazil almost every day (with some variations, of course).
I imagine the common root between Brazil and Cuba must be the African culture.
