Combine the feta cheese, Greek yogurt, sour cream, lemon juice, olive oil, and minced garlic in a food processor or blender. Pulse on medium speed until it starts to coalesce, about 30 seconds.

Continue to blend for 1-2 minutes until smooth, scraping sides as needed. Taste and adjust seasonings with salt or more lemon juice if desired.

Transfer the dip to a serving bowl and use a spoon to create swoops and swirls on the surface.

Drizzle olive oil over the top, sprinkle Aleppo red pepper flakes, and add chopped parsley or mint for garnish.

Serve the dip with pita bread, crackers, or fresh veggies.
