I fry mine up as usual. When they are cooked I cut them in half lengthways. Put some sauce on them (sweet chilli, tomato, bbq) and sprinkle grated cheese on top. Grill them until cheese has melted, YUM! I call it Bec's Butterflied Sausage Parma's!
Ohhhh I do this but with Nando's hot peri peri sauce *drool*

How about devilled sausages?
I make a sausage pasta bake which my family loves.
I boil the sausages first, then remove the skins and cut into bite sized pieces. I also cook up some pasta, we like chilli fettucini.
I mix the sausages and pasta together with a tomato based pasta sauce and add different vegies... sometimes it is just few handfuls of frozen mixed vegies, other times it is peas with finely diced carrot, beans & zucchini and some small florets of broccoli. I then add it all to a baking dish, cover in cheese and bake in the oven until golden. It is yummo.
