To make serving a cooked sausage like Kubasa look more appetising on the plate, instead of just slicing rounds try placing knife on 45 degree angle (to the left) and make oblong slices. To maximise on flavour and make it go further, the thickness of your slice is kinda important too. 3mm or the thickness of a USB plug. Then overlap and fan out the slices around your mustard dip or whatever else you might have on your platter.
