In a large pot, bring water to a boil. Add a generous pinch of salt and pour in pasta. Cook pasta until just al dente (pasta will continue to cook as it cools).
Strain pasta and rinse with cold water. Place back in pot, drizzle with sesame oil, and stir gently. Cover with a tea towel and let cool.
In a large mixing bowl, add shredded cabbage, carrots, chopped cucumber, and onions. Add cooked pasta.
Prepare peanut sauce in a small bowl by whisking together all the sauce ingredients.
Pour peanut sauce over pasta salad and mix gently to combine. Sprinkle with green onion, peanuts, and cilantro. Mix again.
Notes
*To make this a healthier pasta salad, opt for a protein-rich pasta. I used chickpea pasta.
