How to Make It
Cook 5 oz. trimmed fresh sugar snap peas in a medium saucepan of boiling water, stirring often, until bright green, about 1 minute. Using a slotted spoon, transfer peas to a large bowl of ice water. Let peas stand 5 minutes; drain.
Place 1 cup thinly sliced radishes and 2 cups peeled, shaved rainbow carrots in a medium bowl. Sprinkle with 1/4 tsp. kosher salt; let stand while you make the dressing.
Combine 1 cup chopped orange carrots; 3 Tbsp. water; 2 Tbsp. rice wine vinegar; 2 Tbsp. vegetable oil; 1 Tbsp. plain 2% reduced-fat Greek yogurt; 1/2 chopped shallot; 1 1/2 tsp. chopped fresh ginger; and 1 1/2 tsp. white miso in a small food processor or blender. Process until smooth.
In a serving bowl, drizzle peas and carrot mixture with dressing; sprinkle with 2 Tbsp. toasted walnuts.
