Mix the cream cheese together with the sour cream until smooth.
Add the spring onions, pickled chillies, chives, garlic, lemon zest, and a pinch of salt. Mix well.
Transfer the mixture to a serving dish and let it sit for 30 mins to allow the flavors to develop, or refrigerate for an hour.
Before serving, scatter over the remaining chives, add a drizzle of olive oil, and serve with crisps and zaatar.
