In a mini food processor or blender (I used our small Magic Bullet blender) combine the olive oil, vinegar, salt and basil leaves. Use a Microplane grater to grate the garlic into the mixture. Process just until the dressing is smooth and well-blended.
Slice the peaches in half, and then slice each half into four wedges.
Place the arugula in a serving bowl. Top with peaches and prosciutto slices. Tear the mozzarella into chunks and add them to the bowl. Drizzle with the basil vinaigrette and serve immediately.
Notes
Don't over-process the dressing. The heat from the blades can darken the basil leaves, so stop as soon as it becomes smooth.
If you don't have red wine vinegar, you can substitute white wine or apple cider vinegar.
