Rinse your peaches and slice them into 8 roughly even pieces around the pit. Remove the pit and add your peach slices to a large saucepan or shallow pot.
5 fresh peaches, cored and sliced
Add the sugar and salt to your peaches and simmer over medium heat until the sugar dissolves and the juices release from the peaches and starts to thicken (about 10 minutes)
¾ cup granulated sugar, ¼ teaspoon salt
With your heat still on medium, add the cornstarch and stir to integrate. Heat for an additional 5 minutes, stirring occasionally until the liquid has thickened into a syrup.
1 tablespoon cornstarch
Remove your peach cobbler filling from the pan and set it aside to cool for about 5 minutes.
Once your filling is cool enough to handle, lay an egg roll wrapper out flat on a plate, cutting board, or clean counter. Grab a small dish of water and use it to wet your pointer finger, running it around all four sides of the egg roll wrapper to wet the edges.
8 egg roll wrappers
Add about 2 tablespoons of filling to the center of the egg roll wrapper, stretching on a diagonal from one side of the wrapper to the opposite side. Then, fold those two corners over the filling.
Next, grab an empty corner and fold it over the filling, tucking the tip underneath the filling, and rolling it over like a burrito. Use a little bit of water to seal the exposed corner of the egg roll. Repeat steps 5-7 until all of the filling is used up (usually about 8 egg rolls).
