This really isn't anything to write home about, but it's easy and it's my favourite and I use it all the time. Just whisk everything together, taste and adjust seasoning to your liking. Make a bunch and store it in the fridge for easy access. It couldn't be easier to make and is so much better than commercial dressings, which are usually loaded with sugar and preservatives. Did I mention that it's easy?
2 parts super high quality oil such as:
First Cold Pressed Olive Oil / Flaxseed Oil / Hemp Oil / Pumpkin Seed Oil
1 part Unfiltered Apple Cider Vinegar
Whole Grain Mustard to taste
Salt and Pepper to taste
