Preheat your oven to a very hot 220 degrees Celsius with fan and pull out a large baking tray ready to go.
Place the warm water in a bowl and add the yeast sachet from the Simply Wize packet, mix slightly to wet down and set aside for 5 minutes.
Set up your mix master with a dough hook (this could be done by hand but it will take a lot longer!). Then in the bowl place the packet mix of Simply Wize bread, add the vegetable oil and yeast/water mix. Turn on to slow and let the mixture start to come together.
The bread mix will take a few minutes to come together, don't be worried if it looks dry to start with. DO NOT add more liquid! Just simply let the dough hook do the work. Let it mix on slow for a good 5 minutes or until the dough comes together in a smooth and stretchy mix.
Take a large piece of baking paper the same size as your tray and place it on your bench. Sprinkle very well with extra plain flour, any brand will do, you'll want to be very liberal here.
Turn your dough out onto the floured baking paper (it can be quite stretchy, sticky and a bit hard to deal with. Flouring your hands well will help reduce this.) Sprinkle the dough ball with extra flour and start to work it with your hands, just turning it roughly to smooth out and make a ball.
Using a very well floured rolling pin start to roll it out into a rectangle shape the same as the tray approx 55cm x 30cm.
Place the vegemite in a small dish and microwave for 20-30 seconds to make it softer. Then using a knife spread it liberally across your rolled out dough. You can always add more if you really really like vegemite!
Sprinkle with grated cheese, ensuring its evenly spread across the dough. You don't need a huge amount here, it might not look like much but it will be enough! Then start to roll your scroll up starting from the shorter end first. If it sticks a little bit to the baking paper, just use it to roll the scroll and pull back gently as you go.
Once you have a nice long sausage roll take a sharp knife and cut into individual scrolls approx 3cm wide. Spread them out as you cut them, onto the baking paper it's sitting on, a few cm's apart and lay them down flat.
Place your tray of scrolls straight into the hot oven for 15-20 minutes. Scrolls will go beautifully golden brown all over when they're ready and the cheese will bubble over.
Serve warm as is for a delicious snack or lunch or allow to cool fully and store in an airtight container for 3-4 days. Scrolls can also be frozen for lunch boxes! Simply wrap one or two tightly in a layer of cling wrap, followed by a layer of al foil.
