Place water and salt into a bowl and stir to mix. When salt is dissolved, add the harina de maiz and mix to combine. You can begin mixing with a spoon, but you will eventually need to mix with your hands. The harina will begin to absorb the water and as you mix the dough will become less sticky. If it still feels too sticky after mixing, let it sit for a few minutes.
Heat a pan on medium-low heat. Place a small amount of oil in the pan and spread it around with a paper towel to cover the entire pan.
To form the arepas make the dough into balls with about ¼ cup of dough using the palms of your hands. After forming the ball, begin to flatten the ball. It helps to wet your hand slightly, so the dough doesn’t stick as you are trying to roll and flatten. You want the arepa to be about ¼” – ⅓” thick.
Place the formed arepas into the pan and allow them to cook undisturbed for 7-8 minutes. Then flip and continue cooking for an additional 7-8 minutes on the other side. The arepas will likely need up to 30 minutes total cooking time to completely cook on the inside.
When the arepas are ready, heat your beans on top of the stove and season as desired. When the beans are heated, you are ready to stuff your arepas. ;;Cut the arepa in half through the center of the arepa leaving a part attached at the bottom. Place the beans and cheese on the inside.
