I've been using bought sausages (various nice flavoured ones work a treat), wrap in puff pastry for years

A nice variant is to slice the sausage open and spoon in a little salsa before wrapping in the puff pastry

Even better is to half cook them, then take out of the oven, put a little bit of yummy cheese on top and back into the oven. The cheese then melts over the pastry

Enjoy :biggrin:
