Step 1: Prepare the Dough

1. In a mixing bowl, combine the pre-cooked cornmeal (masarepa) and salt.
2. Gradually add warm water while mixing with your hands until a soft, pliable dough forms.
3. Let the dough rest for 5 minutes to absorb the moisture.

Step 2: Shape the Arepas

1. Divide the dough into 8 equal portions.
2. Roll each portion into a ball, then flatten it into a disc about ½-inch thick.
3. Make a small indentation in the center of each disc and stuff it with 1-2 tablespoons of shredded cheese.
4. Seal the edges carefully to ensure the cheese doesn’t leak during cooking.

Step 3: Cook the Arepas

1. Heat a non-stick skillet or griddle over medium heat and add a small amount of butter or oil.
2. Place the arepas on the skillet and cook for 5-7 minutes on each side, or until golden brown and crispy.
3. Press gently with a spatula to ensure even cooking.

Step 4: Serve Warm

1. Remove the arepas from the skillet and let them cool for 1-2 minutes.
2. Slice them open to reveal the melted cheese and serve immediately.
