Step 1

Grease a heavy skillet with a little olive oil. Arrange the pork in the skillet. Drizzle the pork with the remaining olive oil and sprinkle with salt and pepper.

Step 2

Pour water into the skillet until it covers the pork by 1 inch.

Step 3

Cover the skillet and bring the water to a simmer. Reduce the heat to maintain a simmer and cook, covered, for 1 hour.

Step 4

After 1 hour, remove the lid form the skillet and continue to simmer for an additional hour, until the liquid has completely evaporated and the pork beings to fry in the skillet.

Step 5

While the pork is cooking, place the sweet potato in a saucepan and cover with water. Boil the whole sweet potato until it is fork tender, roughly 45 min. When cooked, remove the sweet potato from the water and let it cool slightly. Once cooled, peel the sweet potato and slice it into rounds about a ¼ inch thick.

Step 6

Once the pork liquid has reduced completely out of the skillet, continue cooking the pork until it is golden brown. Flip the chops and brown them on the other side. Remove the pork from the skillet.

Step 7

(If desired,) Add a little oil to skillet, if necessary, and add your cooked sweet potato rounds. Fry the sweet potato slices until golden on both sides.
