Soba, Japanese buckwheat noodles, are ideal for salads because they taste particularly great when served cold. Crunchy vegetables are highlighted here, adding lots of crisp, fresh texture. Substitute with any raw vegetables you have on hand, such as cabbage, carrot, fennel, asparagus, broccoli or cauliflower. The spicy peanut sauce is very adaptable: If you don’t want to use peanut butter, you can use any nut or seed butter, like cashew, almond, sunflower or even tahini. Both the soba and the peanut sauce can be prepared ahead of time and stored in the fridge overnight, but wait to combine them until you are ready to eat for the best texture and consistency. The peanut sauce thickens as it sits, so add a tablespoon or two of water to loosen it up, if necessary.

Preparation

  1. Step 1

    Bring a pot of salted water to the boil. Add the soba, stir to prevent sticking, and cook according to package instructions until just tender. Rinse under cold water until the noodles are completely cold.

  2. Step 2

    Meanwhile, make the sauce: In a medium bowl, combine the peanut butter, soy sauce, maple syrup, lime juice, sesame oil, chile oil or hot sauce, and garlic. Add ¼ to ½ cup water, 1 tablespoon at a time, and whisk until the sauce is a pourable consistency. Taste and add more chile oil or hot sauce as desired; set aside.

  3. Step 3

    Cut the zucchini or cucumber and radishes into ⅛-inch thick slices, then cut into thin matchsticks. Slice the peppers into ⅛-inch pieces. Place them all in a large bowl.

  4. Step 4

    Loosen the soba noodles by running them under some water, then allow to drain again.

  5. Step 5

    Add the soba noodles to the vegetables, add the remaining 1 tablespoon sesame oil and toss to combine.

  6. Step 6

    When you are ready to serve, drizzle with spicy peanut sauce and top with peanuts, scallions and cilantro. Serve immediately, with lime wedges alongside.

Because the processed peanut butters emulsify more readily into the sauces… because of the added stuff, oils in them. I won’t use them and like you always am able to make great results with natural peanut butter …

Beto

I like a little fresh grated ginger and chopped cilantro in my peanut sauce.

Acfh

Why not natural peanut butter? Also can I use spiralized zucchini or summer squash noodles?

Laurie

This was quite good! I doubled the recipe and had to add at least 1/2 cup of water to thin out the sauce. But 20 minutes?? It took me almost that long to measure the peanut butter!

MY Weber

Very tasty. Added tofu cubes that I browned and cooled and didn't have peanuts, so used cashews that I roasted in a pan with some chili lime seasoning. Natural peanut butter worked fine - maybe a little lumpier, but tasted good.

Emma

This was excellent - I used chili garlic sauce in place of the chili oil for the dressing and added a couple of tablespoons of tahini.
