Basic Arepas are almost the same as polenta. Usually they are served with sliced Jack or Mozzerella cheese on top. Some people split them and put in a filling then grill. Sometimes topped with spicy salsa .They are served at a lot of street fairs in Florida along with Jamaica meat patties. They sell here from stand for $3.00 they cost about >.25 to make.
There is a Mexican food co. In Miami that sells them flash frozen to almost all the places down here. They are made in advance and they are pretty good.. Really there is not to much in them that can go bad if wrapped and refriged correctly.
