To make the dressing, whisk together the olive oil, red wine vinegar, honey, salt and pepper.
Create a bed of spinach in a large salad bowl. Add the sliced peaches and sliced avocados on top. Sprinkle with feta cheese and pecans. Pour the dressing over the salad and top with fresh torn basil.
Notes
Make Ahead: You can make the dressing up to 7 days in advance and you can prepare most of the salad up to 1 day in advance. Storage: Store any leftovers in an airtight container for 2 to 3 days.
