Heat 1 teaspoon vegetable oil in a 8 inch non-stick fry pan on medium low heat. Pour in a quarter of the egg mixture and swirl it around to coat the bottom of the pan. Allow egg to cook and set. This should take about 1 minute.
Flip the omelet over and let it cook for another 30 seconds. Slide cooked omelet out of the pan onto a plate. Do the same 3 more times for the remaining egg mixture.
Cut the 4 omelets into halves.
Place a sheet of spring roll wrapper on a clean work surface with one of the pointed ends towards you. Place 2 tablespoons of Jiu Hu Char on the wrapper. Roll half an egg omelet into a mini log and place beside the Jiu Hu Char. Then place a fish stick on the top of the Jiu Hu Char.
Fold the pointed end over the filling. Then fold in both the right and left sides of the wrapper.
Moisten the remaining edges of the wrapper with a little water. Roll and seal. Place spring rolls on a plate in a single layer. Repeat with remaining wrappers and filling.
In a medium sized sauce pan, heat about 1 inch deep oil. Gently lower spring rolls into the oil and fry until golden brown. This will take about 2 to 3 minutes. Remove and drain on a metal strainer.
Serve immediately with sweet chili sauce and mustard.
