Preheat oven to 450 degrees, with racks on upper and lower thirds. On a rimmed baking sheet, toss sweet potatoes with 1 tablespoon oil; season with salt and pepper. Roast on upper rack, until tender, 30 to 35 minutes, tossing halfway through.
On another rimmed baking sheet, toss walnuts with cayenne and 1/2 teaspoon oil. Bake on lower rack,
until golden, 6 minutes.
In a medium bowl, whisk together lemon juice, honey, and remaining 2 tablespoons oil; season with salt and pepper. Add watercress, and toss to combine. Serve topped with sweet potatoes, walnuts, and feta.
This is one of my favorite salads ever. And I love salads. Any green works, I usually do arugula. The flavor combination is amazing!
I make this all the time - it is a favorite on vegetarian night and is my regular Thanksgiving salad. I also substitute arugula for the watercress and I use pecans and leave out the cayenne pepper.
Such a great recipe! I usually like something more substantial for an entree than a salad, but we have this for dinner all the time! It's surprisingly hearty and filling. I usually cant find watercress so I make this with spinach. It's fantastic! Great mix of flavors and textures. Yum.
I made this for Thanksgiving dinner, 2007. It was excellentn n n n n n even substituting hydroponic arugula for the watercress. Will try with watercress eventually. It was a wonderful melange of flavors!
