In a glass jar or bowl, add the champagne vinegar along with the juice and zest of a lemon.Finely chop the shallot and add it to the vinegar and lemon juice. Stir everything to combine and let sit for 10-15 minutes to allow the shallot to quick pickle and become milder.
Then add the mustard, honey, salt, and pepper to taste. Slowly drizzle in the olive oil, whisking as you add it.
Once the dressing is well combined, add the chopped herbs and mix again. Store covered in the fridge for up to 1 week.
