Skinless Sausages why they disintegrate?
They disintegrate simply because the skin of normal sausages is what holds them together, and that's not there. Cooking them in the oven using non-stick sheet (this is one brand but there are others) is probably the best way to keep them intact, but possibly not what you want to do. They also stay together under the grill (broiler) but watch for them leaving bits behind on the bars of the grill pan. If you really want to fry them, be gentle, and tilt the pan to turn them at least until the outside is browned and a bit stronger.
