Put all the vegetables and sausages on a baking tray. Sprinkle over the thyme and black pepper, and drizzle with the olive oil. Stir around so everything has a thin coat of oil and thyme. Drizzle a little balsamic vinegar over the top.
Bake in the oven for 40 minutes at 180C until everything is cooked through.
If you can't get this brand of sausages, feel free to use whatever sausages you pefer. You can skip the parboiling stage and just put the potatoes straight in the tray but you may need to cook it for a little longer in the oven. Cover with foil if it looks like the other ingredients might get overcooked.Nutritional information is approximate and a guideline only
