Sausage roll is a factory-made abomination - a soggy, processed pastry filled with questionable meat by-products and preservatives. You wouldn't feed this to your worst enemy, let alone your family. Just make a real sausage and bake it with some veggies.
Why trash
Mystery meat in refined pastry — the British gas station staple.
Try instead
Grass-fed beef sausage with eggs and vegetables.
