These arepas are ideal as a snack or appetizer. To serve as a main dish for six, double the recipe and plate two topped arepas per diner.
Arrange arepas on a platter. Layer each arepa with 1 mozzarella slice and about 1/3 cup tomatoes. Sprinkle tomato layer evenly with pepper and salt. Drizzle with oil, and top with basil.
