Mix the vinegar and oil with the mustard. Chop the shallots very finely (you can also use spring onions instead of shallots), wash and chop the lemon thyme, parsley and chives. Mix the herbs, the vinaigrette, and pepper and salt.
Boil the jacket potatoes, peel them and cut them into slices, pour the dressing over the warm potatoes, mix and let steep, if necessary season with salt and pepper.
Can be served lukewarm or cold and fits perfectly in the picnic basket or with grilled food!
