Step 1

Preheat the oven to 400°F and line a baking sheet with parchment paper. Spread the diced beets on the parchment paper, drizzle with 1 tablespoon of oil, celery seeds, salt, and pepper and toss. Roast for 20 minutes, or until tender and easily pierced with a fork.

Step 2

Prepare the soba noodles according to package directions, but slightly undercook them to al dente. Drain, rinse with plenty of cold water, and transfer to a mixing bowl.

Step 3

In another mixing bowl, combine the scallions, cucumber, and white beans. Whisk the dressing ingredients together in a glass measuring cup or bowl, pour half over the bean and vegetable mixture, and toss. Add the remaining dressing to the soba noodles and toss.

Step 4

Divide the soba noodles among serving bowls and twirl into a mound in the center of each bowl. Spoon the bean and vegetable mixture over the soba, garnish with roasted beets, and sprinkle with roasted walnuts.
