To make the dressing, combine all ingredients in a mason jar and shake. The dressing will turn a dark brown. Store in the fridge and use as needed. This quantity will make enough for 2-3 salads.
For the salad, finely chop the cucumbers, tomato, bell pepper, onion and parsley.
Place the chopped vegetables in a bowl and drizzle over roughly ¼ cup of the salad dressing.
Stir to combine. Taste and adjust for salt and more dressing as needed.
