Place one egg roll wrapper on a clean work surface with one corner pointing toward you.
Spoon about 1 tablespoon of the cooled turkey filling onto the lower portion of the wrapper.
Fold the bottom corner over the filling, then fold the left and right corners toward the center. Continue rolling tightly toward the remaining corner.
Brush the final corner lightly with water and finish rolling to seal. Repeat with the remaining wrappers and filling.
Fry the Egg Rolls
Heat the frying oil in a deep skillet or pot. Working in batches, carefully add the egg rolls without overcrowding the pan.
Fry, turning occasionally, until the egg rolls are crisp and golden brown on all sides.
Transfer the cooked egg rolls to a wire rack or paper towel-lined plate to drain.
