Bring a pan of water to a boil and cook the eggs for 6-10 minutes depending on the preferred level of doneness. Once cooked, immediately run under cold water until the eggs have cooled. Peel, and set aside.
In a large bowl, mix all the other salad ingredients together.
To make the dressing, whisk together the vinegar and mustard. Then, slowly pour in the oil a few drops at a time, whisky constantly to allow the oil and vinegar/mustard mix to emulsify. Finish with the chopped herbs and season to taste.
Spoon into a serving bowl and serve with the eggs cut in half on top.
