Let’s create this beautiful and easy grilled peach dessert:

1. Preheat Grill and Prepare Peaches:

• Preheat your outdoor grill or stovetop grill pan to medium heat (about 375-450°F or 190-230°C). Clean the grates well and lightly oil them if prone to sticking (though the oil on the peaches helps).
• Wash and dry the ripe peaches. Carefully cut them in half along the seam and gently twist to separate. Remove the pits.

2. Oil and Grill the Peaches:

• Lightly brush the cut side of each peach half with a little extra-virgin olive oil.
• Place the peach halves, cut-side down, directly onto the hot grill grates or grill pan.
• Grill for about 3 minutes, or until distinct char marks form and the peaches have softened slightly. Avoid moving them around too much during this time to achieve nice grill marks. The goal is to caramelize the cut surface, not to cook them until completely mushy.

3. Prepare the Spiced Walnut Topping:

• While the peaches grill (or just before/after), prepare the topping. Ensure your walnuts are toasted (see Tips if not already toasted) and coarsely crushed.
• In a small bowl, combine the ½ cup of crushed toasted walnuts, ½ teaspoon ground cinnamon, and ¼ teaspoon sea salt. Mix well.

4. Assemble and Serve:

• Carefully remove the grilled peach halves from the grill using tongs and place them (grilled side up or down, your preference) on serving plates or in bowls.
• Add a generous scoop of vanilla ice cream alongside or nestled next to the warm grilled peaches.
• Sprinkle the prepared spiced walnut mixture generously over the peaches and/or the ice cream.
• Serve immediately while the peaches are warm and the ice cream is cold and creamy. Enjoy!

An incredibly simple yet elegant summer dessert!
