Chop sausage into bite size chunks. Put olive oil into a frying pan and fry sausage on high heat. Let the fat from the sausage come out into the oil. Cut the pepper into bite size squares. Turn the sausage and add the pepper to the pan. Add a splash of vinegar and the parsley and then give everything a mix. Skewer pieces of sausage and pepper with toothpicks and put onto a warm plate and serve.
