Cut the new potatoes in half. Place them in the baking tray and drizzle with oil. Then bake for about 10 to 15 minutes. Alternatively you can par boil the potatoes for 10 minutes.
Next, add all the vegetables to the baking tray. Drizzle everything with some more oil and add the spices and herbs. Season and mix well, then place the sausages on top. Bake for around 20 minutes.
Remove the tray from the oven and pour in the chicken stock and give everything a stir. Turn the sausages over to brown on all sides.
Place back in the oven for another 20 to 30 minutes until all the veg is cooked through and the sausages are nice and brown.
