Place a pork sausage on the edge of a dumpling wrapper. Apply water to the edge of the wrapper and roll it tightly to seal. Repeat for all 5 sausages.

Heat salad oil in a frying pan over medium-low heat. Place the rolls seam-side down and cook for about 1 minute. Roll them around and cook for another 2–3 minutes until evenly browned.

Push the rolls to the side of the pan and wipe off excess oil with a paper towel. Turn off the heat, evenly distribute shredded pizza cheese in 5 spots in the pan, and place the rolls on top of the cheese. Heat on low until the cheese melts and becomes crispy.
