Chicken, Leek and Brioche Crumble

A creamy savoury crumble simple to prepare and perfect for an everyday family meal. You can prepare this in advance and chill until you are ready to cook making it the ideal fuss free evening option. Using Brioche gives the bake a rich buttery flavour but you could use any quality bread. Make this gluten free by using an artisan style gluten free loaf instead of brioche.
