1. Slice the peaches thinly and add them to your salad bowl. Finely chiffonade your basil and sprinkle it over the peaches, setting a little aside for garnish.
2. Dice your red onion and tomatoes and add them to the bowl with the peaches and basil.
3. For the dressing, combine the olive oil, minced garlic, rice vinegar (or balsamic), red pepper flakes, sea salt, and honey Dijon mustard in a separate bowl or jar. Whisk or shake well to combine.
4. Pour the dressing over the vegetables and toss gently to coat everything evenly.
5. Add your burrata and prosciutto to the salad. Arrange the garlic crostinis around or within the salad.
6. Drizzle more olive oil over the burrata and salad, and garnish with the reserved basil before serving.
