• 2 Tbsp. plus 1/4 cup extra-virgin olive oil
• 4 thick slices crusty bread , cut into 1/2-inch cubes (or 8 thin slices)
• 1 tsp. finely minced shallot
• 1/2 tsp. salt , plus more to taste
• 1/4 tsp. freshly ground black pepper , plus more to taste

• 1 large bunch (about 8 cups) arugula , ends trimmed, washed, dried, and chopped into 2-inch pieces
• 1/3 cup black olives (preferably oil cured), pitted and halved

To make croutons: Heat 2 tablespoons olive oil in a medium skillet until simmering. Add bread and fry, tossing until crisp and golden on all sides. Set aside to cool slightly.

To make dressing: In a small bowl, combine minced shallot, salt, pepper, and vinegar. Whisk in 1/4 cup olive oil.

Toss arugula with dressing in a large bowl. If desired, add more salt and pepper to taste. Divide greens among 4 plates. Scatter olives and croutons over each plate, then lay mozzarella slices on top.
