Make the dressing: Add ½ cup creamy peanut butter, ⅓ cup soy sauce, ¼ cup lime juice, 2 tablespoons maple syrup, 2 teaspoons ginger (grated), 1 to 2 cloves garlic (grated), and 2 teaspoons sriracha to a bowl or blender.Whisk or blend until smooth, then add water, 1 tablespoon at a time, until the dressing is creamy, pourable, and coats the back of a spoon. Set aside.Tip: A blender makes the smoothest dressing, but a whisk works too.
Cook the noodles: Bring a large pot of unsalted water to a boil. Add 8 ounces soba noodles and cook according to package instructions (usually 4 to 5 minutes) until al dente. Do not overcook.Drain the noodles immediately into a colander. Run cold water over them while tossing and rubbing the noodles with your hands for 60 seconds. This removes excess starch and prevents clumping. Drain thoroughly.
Coat the noodles first: Place the drained, cold noodles in a large mixing bowl. Pour about ¾ of the peanut dressing over the noodles and toss thoroughly until evenly coated.If the sauce feels too thick, add a splash of water and toss again until silky and glossy.
Add veggies: Add 1 can chickpeas (rinsed), 3 cups red cabbage, 1 cup cucumber, 1 red bell pepper, and 2 green onions to the bowl. Pour the remaining dressing over the vegetables and toss everything together until well combined.
Garnish and serve: Transfer to a serving bowl. Top with the cilantro and roasted peanuts for crunch. If you like, finish with a drizzle of toasted sesame oil for extra nutty flavor and a final squeeze of lime to brighten everything up.

Tips
Make the dressing bold: It should taste a little too strong on its own. The noodles mellow everything out.
Don't overcook the soba: Check early to keep the noodles tender, not mushy.
Rinse well: A thorough cold-water rinse removes excess starch and prevents clumping.
Dress the noodles first: This coats every strand and distributes flavor evenly.
Keep the dressing loose: Add warm water as needed for a smooth, pourable consistency.
Don't skip the lime: It brightens the dressing and balances the richness.
Slice vegetables thinly: You'll get better texture and more flavor in every bite.
Use crunchy vegetables: Cabbage, peppers, carrots, snap peas, and cucumbers all work beautifully.
Make it your own: Swap in whatever vegetables you have on hand.
Storage: Refrigerate in an airtight container for up to 3 days. Reserve extra dressing to refresh leftovers.
