Made this recipe for our office staff for lunch. Got really good feedback and everyone seemed to really like the dressing. However, I think if I made it again I would not do substitute quinoa for the pasta. I just felt like the texture of the cooked macaroni combined with the texture of the spinach made the salad a bit "squishy."
A coworker also suggested adding some chopped chicken as well, but I think it was fine without it.
