In a large bowl, mix the arepa flour and salt.
Gradually add the warm water, stirring continuously until a dough forms. The dough should be moist but not sticky. If it's too dry, add a little more water; if too wet, add a bit more flour.
Knead the dough for about 2-3 minutes until smooth. Let it rest for about 5 minutes.
Divide the dough into 8-10 equal portions.
Roll each portion into a ball, then flatten it into a disk about 1/2 inch thick. Use your hands or a rolling pin.
Heat a griddle or non-stick skillet over medium-high heat. Lightly grease with vegetable oil if desired.
Cook the arepas for about 5 minutes on each side, or until a golden-brown crust forms and they are cooked through. You can also cook them in a preheated oven at 375°F (190°C) for about 10-15 minutes after pan-cooking to ensure they are heated through.
If you prefer stuffed arepas, you can slice them open once cooked and fill them with cheese, meat, beans, avocado, or other desired fillings.
Enjoy your meal!
