Cook sausages on a grill or griddle pan until sausages are cooked through. Ensure you continue turning the chicken throughout to ensure it cooks through evenly.

Heat olive oil in a large frying pan over medium heat. Add the onions and fennel seeds. Cook, stirring occasionally, for about 10 mins or until onions start to caramelize. Add the sugar and vinegar and cook for a further 1 min or until caramelized.

Split breadrolls roll lengthways (Make sure you don’t cut them all the way through). Spread each roll with the chutney or relish. Divide the rocket, brie, sausages and onion mixture evenly among rolls.

Season and enjoy.
