Sausage rolls are generally made with puff pastry. This was my first time trying a filo sausage roll, and I am quite pleased with the result. I am not sure whether I prefer the puff or filo version, they are both good in their own special ways. Assembling the filo version takes a bit more effort. The sheets need to be brushed with butter, and rolled with care since these things are quite fragile. The filo version has lower fat content, which means you can eat more without feeling guilty.
The filling is quite versatile. You can add pretty much anything that makes sense. For a flavor boost, substitute some of the mince with bacon. To add some carrots or other veges to healthify it. I think you can also add some finely diced tofu and it won’t be noticable.
