Peel the sweet potato and cut it into bite-sized pieces.

Soak the cut sweet potato in water for 3–5 minutes.

Pat the sweet potato pieces dry using a kitchen towel.

In a pan, add vegetable oil, sugar, and vinegar.

When the sugar starts bubbling, add the sweet potato pieces and reduce the heat to low.

Cover the pan and cook the sweet potato, flipping occasionally.

Place mozzarella cheese in a serving dish.

Layer half of the cooked sweet potato on top of the cheese.

Sprinkle more mozzarella cheese over the sweet potato layer.

Add the remaining sweet potato on top and finish with a generous layer of mozzarella cheese.
