In a large bowl, whisk the corn meal and salt. 

Prep the lukewarm water. Wet your hands for kneading the dough with your hands. Add in the water one half a cup at a time. Begin using a spatula and combine the water and corn meal to make a dough. Keep adding the water in portions. You are looking for the dough to just come together. It should be moist. Let the dough rest for 30 minutes covered.

Lightly wet your hands with cold water to prevent the dough from sticking.  Divide the dough into equal portions and roll them into balls. Next, form them into ovals. Place a piece of the cheese in the middle of the dough and roll again in your hands.

Heat oil in a skillet on medium high heat. Cook each cheese filled arepas for 3 - 4 minutes per side.

Serve and enjoy!
