Since I have made this dressing, I have never needed to buy anything remotely resembling salad dressing since and it frees up fridge space.
In a 250ml clean empty jar, 1/2 fill with extra virgin olive oil ( maybe 150mls) then add 50mls apple cider vinegar, big tablespoon of honey and a tablespoon of dijon mustard. If you like you can add grated garlic and or Zatar (middle eastern spice mix) say teaspoon of either. Shake up real good and you have enough dressing for 3 or 4 salads. Tastes awesome and good for you. If you have a fav, please let me know. Cheers
