In the bowl of a food processor fitted with a blade, add the chunk of feta in brine (only the piece of cheese, DO NOT add the brine).
Pulse to break up the chunk.
Next, add the yogurt, lemon zest, and creole seasoning.
Pulse until combined.
With the blade running, slowly pour in the cream; starting with 1/4 cup.
Add more if you want the consistency to be smoother.
Take the whipped feta mixture and put in a serving bowl. Sprinkle the parsley over the whipped feta, followed by the olives.
Drizzle with olive oil, and serve with crostini, toasted pita wedges, or fresh veggies.
