My obsession with preserved lemons began here, and it came about thanks to a job I got working in the kitchen of a vegan cafe. I was tasked with coming up with a sandwich, and rather than settle for yet another incarnation of the ubiquitous veggie wrap, I wanted to make something surprising. Something different. Something just bursting with seasoning and spices - something that, let's face it, you don't always find at a vegan eatery.
And then I read about the Tunisian sandwich. Now, a traditional Tunisian sandwich contains tuna and egg - obviously not vegan. But I thought that the other ingredients that are often used - potatoes, capers, black olives, harissa, and of course, preserved lemon - sounded as if they'd hold up pretty well on their own.
