Toast the bread then (optionally) spread it with a little Marmite. grate (shred) or crumble the cheese and spread it evenly over the toast. Place this under a hot grill (broiler) until the cheese just begins to melt. Slice the cooked sausages either lengthways (as I prefer) or in round slices (as shown above) and place on top of each toastie. Return to the grill for a few more minutes until the cheese begins to bubble.
Alterntively (as shown on the right) you can crete "mini-toasties" for the kids by cutting a baguette and putting a slice of sausage on each one. Either way, a great snack for children and adults alike!
