Cook soba noodles, drain and rinse them under cold water to cool them down. Keep the noodles aside.
In a mixing bowl, add sesame oil, soy sauce, rice vinegar, honey or maple syrup, peanut butter, minced garlic and grated ginger. Stir all ingredients together until mixed well.
Add cooked and cooled soba noodles to the bowl with the dressing. Mix well until dressing coated the noodles evenly.
Add chopped cucumber, carrots, coriander leaves and green onions and mix everything together to spread the vegetables equally among the noodles.
Cover the bowl and kept it in the refrigerator for at least 30 minutes.
Before serving, sprinkle some sesame seeds for garnish.
Chilled Cold Sesame Noodle salad is ready to serve.
