Peel the pineapple, remove the stalk and cut the flesh into cubes (approx. 1.5 x 1.5 cm). Melt 30 g butter in a pan. Add the pineapple, sprinkle with sugar and caramelise for about 5 minutes, stirring occasionally.
Remove the pineapple from the pan.
Cut each veal sausage into about 6 pieces. Halve the bacon slices. Wrap 1 bacon strip around 1 piece of sausage. Put pineapple and white sausage alternately on the skewers, grill on a baking tray under the hot grill for about 5 minutes, turning, until the bacon becomes crispy.
Sprinkle with sesame seeds about 1 minute before the end of the grilling time. Remove from the oven and serve hot or cold.
