How do I make a nut-free Dubai chocolate bar for allergies?

Replace pistachio cream with sunflower seed butter or pumpkin seed butter for a nut-free filling. Sunflower seed butter has a mild, slightly sweet flavor that works well with tahini (which is sesame-based — verify this is safe for your allergy profile). Toast the kataifi with sunflower oil. Label clearly if gifting, as cross-contamination in shared kitchens is a real concern for people with severe nut allergies.
