Brown your sausages in a pan over a medium low heat then push to the sides to make room in the middle of the pan
Go in with butter and then your sliced onions and fry for a few minutes until soft
Then add your sugar, thyme, mustard, salt and pepper to the onions and mix with everything in the pan
Then go in with your flour and mix until it’s all cooked out
Then add your bone broth cubes or stock and mix
Add your bayleaf then lay your puff pastry over the top, prick holes in it with a fork and then get it in the oven for 30 mins at 180oC fan
Take it out, flip it onto a plate, remove the bayleaf and sprinkle over your chives
