Fry the onion in a little margarine until cooked to a golden colour. Push the onion to the edges of the frypan and turn the heat up to high. When the pan is hot add the minced beef, and turn regularly until the meat is browned. Turn the heat down again, and add the Worcestershire sauce, tomato puree and herbs, and mix through. Turn heat to very low and place a lid on the frypan. Cook the sauce for 10 minutes or for however long it takes the pasta to cook.
Serve with pasta, OR as a jaffle filler, OR on a pizza base (see Josh’s recipe for Kakadu Pizza)
