Add about 3/4 cup of cold/room temperature water to a large plate. You want enough water so you can submerge your rice paper, but not too much that the water overflows when you dip your rice paper sheet.
Dip your rice paper sheet into the water. Flip it, then dip again.
Transfer the wet rice paper sheet onto another plate, then add about 3-4 Tablespoons of your spicy noodles to the middle. Use either chopsticks or a fork to help you with the noodles.
(Optional) Add the shredded cabbage or any other vegetable of choice.
Wrap into a spring roll shape by folding in the left and right edges of the rice paper. Then fold the bottom part up and roll (see pictures above).
Flip your spring rolls so that the nice part faces upwards, then transfer to your serving plate.
Repeat with the remaining spring rolls.
(Optional) If you want crunchy spring rolls, either air fry for 10 minutes at 400℉ (205℃), or pan fry with a bit of oil for 3-4 minutes on each side until they turn golden brown.
Serve as is or with (spicy) mayo, and enjoy!
