!! Make 4 portions without cheese-- reference recipe link
1. If mozzarella cheese block: Shred 1/3 of the mozzarella and cut remaining 2/3 into 1/2-inch cubes. Transfer shredded cheese to a large bowl and cubed cheese to a medium bowl. Skip if given ingredients

2. Add cornmeal, salt, and warm water to the shredded cheese and mix to combine. Set aside for 10 minutes to allow cornmeal to absorb liquid. The mixture should resemble soft Play-Doh.

3. Preheat the oven to 200 degrees F (95 degrees C).

4. With damp palms and fingers, place 1/4 cup arepa mixture into your palm and flatten into a 2 1/2-inch disk. Place 3 to 4 cubes of the mozzarella into the center. Gently fold edges of dough over to cover mozzarella cubes completely, patting to form a cake. Repeat until all dough and cheese has been used.

5. Heat oil in a large nonstick skillet over medium heat. Add 3 or 4 arepas and cook until both sides are golden brown and charred in spots, 4 to 5 minutes per side. Remove to a parchment-lined baking sheet and season with a pinch of the remaining salt. Place in the preheated oven to keep warm. Repeat with remaining oil, arepas, and salt.
