Heat the oil in a large frying pan and fry the sausages until just golden.
Add the onions and fry until they are tender and golden brown.
Then add the lager, honey, mustard and Worcestershire sauce and simmer until the lager has reduced to a thick caramelly sauce.
Serve the sausages and onions in chunks of French bread with ketchup.
Cooks tip: Depending on how much onion you like with your sausages, you may like to increase the quantities for the sauce. If you have any left over, you can store it covered in the fridge for up to 2 days.
