On a large serving plate or platter, arrange the baby arugula in a circular wreath pattern, leaving a small open center. Gently toss the arugula with a light hand to create height and dimension rather than pressing it flat—this gives the finished salad a more appealing, professional appearance. The arugula will serve as your flavorful, peppery foundation and helps support the other delicate ingredients.
Arrange the halved cherry tomatoes around the arugula wreath in a scattered, artistic pattern. Distribute the marinated mozzarella pearls evenly between the tomatoes, allowing some of the marinade to drip onto the arugula for extra flavor. Tear or roughly chop the fresh basil leaves and distribute them throughout the salad, layering them strategically so they peek through the other ingredients. I find that tearing basil by hand rather than cutting it helps preserve its delicate oils and prevents browning.
Drizzle the balsamic vinaigrette or glaze across the salad in a decorative pattern—try creating thin lines or a light overall coating rather than dumping it in one spot. Follow with a thin drizzle of extra virgin olive oil for richness and to tie the flavors together. Sprinkle the toasted pine nuts evenly across the salad for a subtle crunch and nutty depth. Finally, finish with flaky sea salt and freshly cracked black pepper to taste. I prefer adding the dressing just before serving so the greens stay crisp and bright rather than becoming soggy.
Bring the finished Caprese salad wreath to the table right away while the arugula is still crisp and the flavors are at their peak. This bright, fresh salad is best enjoyed immediately after assembly.
