1. Combine first 4 ingredients, stirring with a whisk. Gradually drizzle in olive oil, stirring constantly with a whisk. Stir in chopped mint.
2. Combine lettuce mix and peach wedges in a large bowl. Drizzle lettuce mixture with dressing; toss gently to coat. Arrange about 2 cups salad in each of 4 bowls; top each serving with 3/4 ounce prosciutto, 1 piece of ricotta salata, and about 2 teaspoons sunflower seed kernels. Garnish with small mint leaves, if desired.
Wine note: With this salad, you need a wine that can take the sweetness of peaches and honey. Riesling's the ticket. It has a honeyed character built right in, and it adores cured pork. Apex Cellar's 2008 Riesling from Washington state's Columbia Valley (about $18) would be a great choice, with a spritz of lemon offsetting its off-dry stone fruit. --Sara Schneider
