Prep ahead: Dressing keeps 1 week in the fridge; toasted pecans keep 5 days at room temp in an airtight container; washed and dried arugula stays crisp in a paper-towel-lined container for 2–3 days. Slice peaches just before serving. Pro tips: Always salt the peaches; don't skip the mustard in the dressing (it emulsifies); crumble goat cheese cold for distinct pieces; double the pecans because they disappear. Variations: Add grilled chicken, smoked salmon, or halloumi for protein. Swap peaches for nectarines, plums, or figs. Make it vegan: skip the cheese, use coconut oil for the pecans.
