Preheat your oven to 200°C .
Peel , wash and very very finely slice the potatoes then rinse in ice cold water .
Take two of the cooked sausages and slice them into thin rounds , then take the remaining two sausages and but off both ends to leave the middle pieces about 10cm long , now slice the end pieces into thin rounds , and then cut the middle pieces into thin slices and keep the slices and the end round pieces for garnish . You can use less amounts of sausages if preferred .
Slice the spring onion into thin rounds and Finely chop the herbs . Then place the milk , cream , salt , pepper and garlic into a bowl and stir to combine all well .
In a medium oven proof dish preferably one with a lid (if not foil will do) , lay a layer of the sliced potatoes across the bottom of the dish then place some of the first lot sausages rounds and evenly sprinkle half the first cup of grated cheese over top followed with the spring onion pieces , sprinkle with some of the chopped herbs and one of the tablespoon of cream cheese place little blobs all over .
Repeat the above process with a second layer , then pour the prepared milk cream mix all over the potato layers then dollop the remaining spoonful of the cream cheese all around then sprinkle half of the remaining half cup of grated cheese evenly over top and sprinkle with remaining herbs then cover with lid or foil .
Once prepared , place in Preheat oven and cook for 1 hour then remove the lid or cover and turn the heat down to 180°C and then add the remainder of the grated , evenly all over top and then cook a further 20 - 30 minutes or until potatoes are cooked through and tender and cheese is melted and golden .
