Wild Arugula Salad with Garlic Croutons, Shaved Parmesam, and Lemon

From Bon Appétit 

Ingredients

• 1 8-ounce piece ciabatta with crust (preferably day-old)
• 1 large garlic clove, peeled
• 1/4 cup plus 3 tablespoons extra-virgin olive oil
• 6 ounces arugula (preferably wild; about 10 cups packed)
• 2 tablespoons (or more) fresh lemon juice
• 3 ounces Parmesan cheese, shaved into strips with vegetable peeler

Directions

Preheat oven to 400°F. Rub crust of bread with garlic clove. Tear bread into 1-inch pieces and place in large bowl; toss with 1/4 cup olive oil. Sprinkle bread lightly with salt; arrange in single layer on rimmed baking sheet. Bake until golden and crisp around edges, about 10 minutes. Cool. DO AHEAD: Can be made 4 hours ahead. Let stand at room temperature.

Place arugula in large bowl. Drizzle with 3 tablespoons olive oil and 2 tablespoons lemon juice, adding more lemon juice, if desired. Sprinkle with salt and pepper. Add 2/3 of croutons and half of Parmesan cheese and toss. Transfer to serving bowl; scatter remaining croutons and Parmesan cheese over and serve. Makes 6 servings

Ingredient tip: Wild arugula is dark green with spiky leaves. It has a more intense flavor than that of regular arugula. You'll find wild arugula at farmers' markets and at some supermarkets.
