Preheat the oven to 220C, fan-forced. Line an oven tray with baking paper. Quarter the unpeeled potatoes. Thinly slice the spring onion. Finely chop the celery.
Step 2 — Bake potato
Put the potato on the lined tray, drizzle with 1 tbs olive oil, season with salt and pepper and toss to coat. Bake for 10 mins (the potato will not be cooked through at this stage).
Step 3 — Add sausages
Add the sausages to the tray with the potato and bake for a further 15 mins or until cooked through (see Kitchen hack).
Step 4 — Make salad
Meanwhile, quarter the apple, remove the core and cut into 2cm chunks. Put 1 tbs white wine vinegar, 2 tsp wholegrain mustard and 2 tsp honey in a large bowl and stir until the honey dissolves. Add the apple, celery, spring onion and raisins and toss to combine. Season with salt and pepper.
Step 5 — Serve up
Divide the sausages, potato and salad among plates. Serve with tomato sauce, if desired, and enjoy!
Step 6 — Kitchen hack
Baking sausages is a nifty trick that prevents oil spattering in your kitchen and gives you extra hands-free cooking time. You can also cook them in a medium frypan over medium heat, covered, for 8-10 mins until cooked through.
