Prepare the Peaches: Wash and slice peaches in half, remove pits, drizzle with olive oil, preheat grill to medium heat (around 400°F), and grill for 2-3 minutes until marked and softened.

Assemble the Salad: In a large bowl, add mixed greens, chopped grilled peaches, blackberries, avocado, vegan feta, shallots, and pecans.

Prepare the Dressing: In a small bowl, whisk together minced garlic, Dijon mustard, maple syrup, lemon juice, apple cider vinegar, olive oil, and salt until combined.

Dress the Salad: Pour dressing over the salad mixture and gently toss to coat the ingredients without damaging the delicate blackberries.

Serve and Enjoy: Transfer salad to a serving dish or individual bowls and enjoy cold at summer gatherings or as a nourishing meal.
