Combine all ingredients above (including yogurt (omit if whole30), spices, water, lemon juice, garlic, olive oil etc.).
Mix well until fully combined and smooth.
Adjust salt and seasonings to taste.
Also add a little bit more water if needed to thin out the dressing to your desired consistency. I prefer mine just thin enough so it can be stirred easily but still thick - almost like the consistency of ranch!
Garnish with za’atar if desired.
Serve as a dressing for salads or as a dip!
