Plan ahead this dressing has a 24 hour chilling time to blend the flavors, don't even think about serving this right away! this must be made on a food processor for the feta to combine properly --- the success of this dressing will highly depend on the quality of olive oil, oregano and feta cheese that you use I recommend purchasing those ingredients in a Greek grocery store --- cooking time is 24 hour refrigeration time ---- also see my highly-rated recipe#66596 --- and my mayonnaise-based recipe#359292
