Step 1

Preheat oven to 350°. Toast pistachios on a rimmed baking sheet, tossing once, until golden brown, 8–10 minutes. Let cool, then coarsely chop.

Step 2

Meanwhile, cook green beans and sugar snap peas in a pot of boiling salted water until no longer raw but still very crunchy, about 2 minutes. Using a slotted spoon, transfer to a bowl of ice water and let sit until cold, about 3 minutes. Drain, pat dry, and thinly slice into bite-size pieces.

Step 3

Blend herbs, oil, vinegar, mustard, and 2 Tbsp. toasted pistachios in a blender, adding water by the tablespoonful if dressing is too thick, until smooth and the consistency of heavy cream. Season with salt and pepper.

Step 4

Toss beans, peas, broccoli, pea shoots, quinoa, and remaining toasted pistachios in a medium bowl to combine. Drizzle salad with dressing and toss again to nicely coat everything; season with salt and pepper.
