01 - Preheat a grill or grill pan to medium-high heat. Brush the nectarines lightly with olive oil.
02 - Grill the nectarines, cut side down, for 2–3 minutes until grill marks appear and nectarines are slightly caramelized. Flip and grill for another 1–2 minutes. Remove and let cool slightly, then slice each half into wedges.
03 - In a large mixing bowl, toss arugula, cherry tomatoes, and shallot with 2 tablespoons olive oil, salt, and pepper.
04 - Arrange the dressed arugula mixture on a large platter or individual bowls. Top with grilled nectarine wedges.
05 - Tear the burrata balls and place over the salad. Sprinkle with toasted pistachios.
06 - Drizzle with balsamic glaze. Finish with an extra crack of black pepper if desired. Serve immediately.
