The peppery addition of arugula to this is lovely and spicy. With all the great summer peaches around, this is a winner. If the white peaches are looking better than the yellow, replace the onion with red onion for good color contrast.
1/4 cup mayonnaise
1/4 sup sour cream
1/4 cup buttermilk
2 tbsp chopped mint
2 tbsp chopped Italian parsley
2 tbsp snipped chives
1 tsp apple cider vinegar
Salt and freshly ground pepper
1lb thickly sliced bacon
1/4 cup light brown sugar
1/2 tsp cayenne pepper
3lbs Vidalia onions, or other sweet onions, cut into 1 inch thick slabs
Extra virgin olive oil, for brushing
4 large, ripe peaches, cut into 1/2 inch wedges
2 – 3 cups baby arugula, for serving
Preheat the oven to 325 F
In a small bowl, whisk the mayonnaise with the sour cream, buttermilk, mint, parsley, chives and vinegar and season with salt and pepper. Refrigerate.
Line a large rimmed baking sheet with parchment paper. Arrange the bacon slices on the sheet in a single layer and sprinkle with brown sugar and cayenne pepper. Bake for about 25 mins, until caramelized. (the bacon will crisp as it cools). Let cool, then cut or break the bacon into bite-size pieces.
Meanwhile, light a grill or preheat a grill pan. Brush the onions with olive oil and season with salt and pepper. Grill over a moderate heat, turning occasionally until softened and browned.
Separate the onions into rings.
Brush the peaches with olive oil and grill over a moderately high heat until tender, 2 minutes.
Transfer to a plate.
On a large serving platter, arrange the arugula in a layer. Top with the peaches, onions and bacon.
Drizzle the dressing over the salad and serve
