hassan: my name's hassan saidani. with my uncle for almost 12 years. reporter: lablabi is a baguette, topped in different ways and freshly prepared. vital ingredients are the hot chili paste harissa, and chickpeas. soaked in water the night before, they're cooked in the morning. customers then choose additional toppings. such as spices, cooked vegetables, garlic, sardines, olives, and tuna. demand is huge. saidini prepares one lablabi after another. what makes this sandwich so popular? >> i like the taste, how spicy it is, and chickpeas are good for you. i just like how it tastes. it's not as unhealthy as other sandwiches that contain burnt oils and lots of fried ingredients that aren't fresh. i feel this one is better for you than other sandwiches. reporter: at prices between 1 and 1.5 dinars -- barely 50 euro cents -- it's affordable, too. lablabi has a long tradition in bizerte. >> it began in the 1970's. lablabi started to appear in small roving carts like this one and met with great success here in bizerte. peopl
