1. Combine 1 tablespoon oil, rind, juice, and chicken cutlets; let stand 5 minutes.
2. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Sprinkle chicken evenly with 1/2 teaspoon salt and 1/4 teaspoon pepper. Add chicken to pan; cook 2 minutes on each side or until done. Remove from heat; keep warm.
3. Combine tomatoes and arugula in a large bowl. Combine vinegar, herbes de Provence, mustard, garlic, remaining 1/4 teaspoon salt, and remaining 1/4 teaspoon pepper; gradually add remaining 2 tablespoons oil, stirring vinaigrette constantly with a whisk. Drizzle the vinaigrette over salad; toss gently to coat. Divide salad evenly among 4 plates. Cut chicken cutlets across the grain into thin slices; arrange 1 sliced cutlet over each salad, and top each serving with about 2 teaspoons olives.
