Tarragon—Whether you love it or hate it, you have to agree: It’s distinctive. It gives a very interesting flavour to this Quinoa Roasted Veggie Salad with Gail’s Caper-Walnut Vinaigrette. Gail who? Gail Simmons is the lovely, big-hearted foodie maven responsible for this keeper. Thank you Gail, and thank you Food & Wine Magazine for sharing Gail’s delectable sauce.
