Shitake, Leek & Arugula Salad

(recipe from a magazine, not sure which one)

1/2 lb. shitake mushrooms, stemmed and sliced 1/4-inch thick
1 medium leek, white and light green parts only, halved lengthwise and sliced 1/8-inch thick
3 Tbsp. olive oil
Kosher salt and freshly ground black pepper
1 lemon
3 lightly packed cups baby arugula

Position a rack in the center of the oven and heat the oven to 450F.

In a medium bowl, toss the mushrooms, leek, oil, 1/2 tsp. salt, and 1/4 tsp. pepper.

On a small baking sheet, scatter the mushrooms and leeks in a single layer.  Roast until the vegetables are tender, about 15 minutes. 

Combine the arugula and roasted vegetables in a large bowl.  Squeeze about 1 Tbsp. juice from the lemon onto the vegetables and toss to combine.  Season to taste.

(For a convenient dinner, roast some 6 oz. salmon fillets along with the vegetables on the baking sheet.  Serve together.)
