1.Place 1 tbsp oil, thyme and garlic in a bowl, season to taste and stir to combine. Add cutlets and toss to coat. Wrap each cutlet in a prosciutto slice.
2.Heat a large frying pan over medium heat. Sear lamb, turning occasionally, until browned all over (3-5 minutes); rest for 5 minutes.
3.Meanwhile, tear mozzarella, and combine with peaches, shallot and watercress in a large bowl. Add remaining oil, vinegar and lemon juice, season to taste and toss to combine.
4.Divide lamb and peach salad between plates. Scatter with basil and freshly cracked black pepper; drizzle with oil.
Produce tip: use the ripest stonefruit available. Alternatively, this works equally well with watermelon or rockmelon.
