Start by dividing the cucumber and core it using a spoon. Then slice into half moons. Place in a bowl and add rice vinegar and stir to combine. Set aside.
Cook your noodles according to the description unless using shirataki noodles as I did.
Preheat a nonstick pan over medium heat.
Fry the garlic and white parts of the scallion until golden brown.
Combine gochujang, tamari/soya sauce, peanut butter, rice vinegar and sesame oil in a bowl. Then add to the hot pan and stir to combine until incorporated with the garlic and scallion.
Add the noodles and fry for a few minutes until warm.
Preheat another nonstick pan and add the cashew nuts and dry roast until golden brown.
Divide the noodles between two bowls and top with cashew nuts, cucumber, thinly sliced sugar snaps, chili flakes (if using), cilantro and mint. Serve warm.
