I simply use sausage meat, and add a diced onion and either some tomato sauce OR BBQ sauce and mix it all up. These are never bland! They're always a hit!! Sausage mince/meat with just breadcrumbs, salt and pepper would be pretty ordinary!!!

You can use different kinds of sausages though to make it taste a little bit different...... if you go to a butcher or deli and take a look at their snags, you'll find some that you can use (just squeeze out the meat from the sausage casing and then add the onion and sauce). I've used BBQ Sausages before or Beef & Tomato Sausages and they've turned out REALLY well.
