I use to get a “trk special” at the local takeaway - they literally added it to their menu board because I got it so frequently and other people who heard also got it.
It was three pieces of bread, all the salads (tomato, lettuce, carrot, onion, cucumber, beetroot) and aioli sauce on the bottom, then a spicy kebana sliced horizontally with a heap of pepper sauce and a slice of cheese on the top layer. Quick toast with butter so the outer slices gave a tiny bit of crisp and the cheese starts to sag and voila.
Another one they added to their menu board was the “xxxx trucks special” which was named after a local business. All the apprentices there used to buy this one because it was cheap and filling. It was a fresh toasted hotdog roll, with a sausage roll instead of a sausage, and a heap of butter and tomato sauce.
