We’ve created the ultimate Winter week-night meal. This traybake recipe is so easy but the delicious sausages, apple, onion and honey and wholegrain mustard sauce combine to make a beautiful sticky and sweet flavour. The traybake is perfect for feeding the whole family and chucking in leftover vegetables – switch up the parsnips and red onion for other ingredients like fennel or whatever veg you have in the house if you have fussy ones to cater for.
