Mix all the salad dressing ingredients and set aside.
Prep the peaches
Stone the peaches, then slice each peach half into 4 wedges.
Gently toss the peaches with ½ Tbsp olive oil.
Heat a griddle (or do this or your bbq) on medium-high heat and grill the peaches for a minute on each side.
Tip out into a medium bowl and set aside.
Everything else
Peel then slice the shallots thinly, then add to the peaches in the bowl.
Add the rocket leaves to the bowl.
Pour half the dressing all over the peaches, shallots and leaves and very gently mix. You don't want to break the peaches up. If your peaches are soft, then keep them separate, just toss the shallots and leaves. Then place the peaches on the leaves after serving onto individual plates.
Serve Up
Divide the salad onto 2 plates.
Crumble the roquefort all over.
Break up the walnuts with your hands and top the salad with them.
Drizzle the rest of the salad dressing all over and serve immediately.
