Arepas vary from country to country, coming in different sizes and taste...
BUT CAN WE AGREE THEY ALL TASTE LIKE A PERFECT (MUCH BETTER VERSION) GRILLED CHEESE?!
Growing up in south Florida, these became one of my favorite mid-day snack. You can find these being sold at street vendors in highly-populated areas, or even sometimes at a local Latin food place. It's typically made with maize dough or cooked flour. I am more familiar with the arepas made with maize. Arepas are popular in South America, but can also be found in the caribbean countries like Panama, Puerto Rico, and the Dominican Republic.
The awesome thing about arepas is that you can fill them with all sorts of foods, including cheese, eggs, avocado, black beans, and even shredded meat! And because they are so versatile, you may even eat them vegan.
