This creamy milchig spread is wonderfully tangy and versatile. Serve it on toast as a sophisticated substitute for cream cheese, or as a dip with pita chips or cut-up vegetables.
Using a food processor fitted with the S-blade, process the feta, sour cream, lemon zest, and dill. Transfer to a bowl, then drizzle with olive oil and garnish with walnuts.
Transfer to an airtight container and store refrigerated for up to 1 week.
