Add potatoes to a medium-sized pot and cover with cold water.
Add to the stove, bring to a boil, and cook until soft, about 10 minutes.
Remove from the stove, drain, and let cool.
While the potatoes are cooking add the bacon to a skillet and cook until crispy. Once the bacon is fully cooked chop up the bacon and set aside.
In a large bowl add cooled potatoes, chopped bacon, and red onion, set aside.
In a blender or food processor add garlic, olive oil, parsley, chives, tarragon, dill, red wine vinegar, whole grain Dijon mustard, kosher salt, and black pepper.
Process until smooth.
Pour the herb mixture over the potatoes and stir to combine.
Taste and if desired, season with more kosher salt.
