In a medium bowl, combine the apple cider vinegar, honey, Dijon mustard, minced garlic, dried oregano (and any optional dried herbs), salt, and pepper. Whisk until honey is fully dissolved and mixture is uniform.
While continuously whisking, slowly drizzle in the olive oil in a thin stream to create an emulsion.
Continue whisking for about 30 seconds after all oil has been added until the dressing thickens slightly.
Taste the dressing and adjust the seasoning as needed (more vinegar for acidity, more honey for sweetness, more salt or herbs for depth).
If using fresh herbs like parsley, fold them in gently after the dressing is emulsified.
Transfer to a mason jar or airtight container with a tight-fitting lid.
Refrigerate for at least 30 minutes before using to allow flavors to meld.
Shake vigorously before serving to recombine ingredients.
