This is the classic Brooklyn deli macaroni salad, made vegan. Creamy, tangy, and packed with grated carrots, radishes, and peas. It's the perfect cookout side dish that gets even better after a few hours in the fridge.
Combine all the dressing ingredients in a large mixing bowl and mix with a fork until completely blended. Add the radishes, carrots, and peas and set aside while you cook the macaroni.
Boil the macaroni in well-salted water. Drain and rinse under cold water until the pasta is still warm but not too hot to the touch. Transfer to the bowl with the dressed vegetables and toss to coat.
Cover and refrigerate. Wait until the salad is fully cold before tasting for salt and pepper. Stir a few times while it chills to make sure the dressing coats everything.
