Place the pork sausages on a baking tray and cook them in the oven for 20-25 minutes at 200°C or 400°F.
Bring a pan of well-salted water to a boil (½-1 teaspoon of salt to a litre of water).
Cut the new potatoes into bite-sized pieces if needed, then boil them for 20-25 minutes.
Core the apple and then slice it into thin wedges, then place it into acidulated water.
Cut the shallot in half, then peel it and cut it into half-moon-shaped slices as thinly as you can.
Pick and clean the rocket.
Combine the cider vinegar, maple syrup, olive oil and wholegrain mustard in a jar and give it a good shake. You can also whisk it together in a bowl.
2-3 minutes before the potatoes are cooked, heat a frying pan over a medium heat and add the bacon lardons, then cook for 5 minutes, stirring occasionally.
When the potatoes are cooked, drain them, then crush them lightly with the bottom of a cup or glass.
When the sausages are cooked, remove them, and then slice them at a 45° angle/ Place them in a large bowl.
After the bacon has been cooking for 5 minutes, add the crushed potatoes and cook for another 5 minutes before transferring to the bowl with the sliced sausage.
Drain the apple and add it to the sausage mix along with the sliced shallot.
Add the rocket and drizzle with the dressing before tossing and serving immediately.
