Preheat your oven to 220°C/200°C fan/gas mark 7. Boil a full kettle.

Add the sausages to a large baking tray. When the oven is hot, roast the sausages they are browned and cooked through, 20-25 mins.

Turn halfway through. IMPORTANT: Wash your hands and equipment after handling raw sausages. They're cooked when no longer pink in the middle.

Meanwhile, chop the potatoes into 2cm chunks (peel first if you prefer). Halve, peel and thinly slice the red onion.

Pour the boiling water from your kettle into a large saucepan with 1/2 tsp salt on high heat.

Add the potatoes to the water and cook until you can easily slip a knife through, 15-18 mins.

While the potatoes cook, heat a drizzle of oil in a large frying pan on medium-high heat. 

Once hot, add the mixed veg, season with salt and pepper and cook for 2-3 mins. Add a splash of water, cover with a lid (or some foil) and steam-fry until tender, 4-5 mins.

Transfer the veg to a bowl and cover with foil to keep warm.

Pop your pan back on medium high heat and add a drizzle of oil and the sliced onion. Cook, stirring often, until softened, 5-7 mins.

Once the onions are soft, lower the heat to medium and add the balsamic vinegar. Cook until sticky, 1-2 mins.

Add the water for the sauce (see pantry for amount) and bring to the boil. Stir in the red wine stock paste and redcurrant jelly. Simmer until the sauce has thickened slightly, 2-3 mins. Add a splash of water if it's a little thick.

When the potatoes have 1 min left, add the spinach to the same pan. Once the potatoes and spinach are cooked, drain in a colander and return to the pan.

Add a knob of butter and a splash of milk (if you have any) and roughly mash. Season with salt and pepper.

Share the spinach mash between your plates and serve the sausages and veg alongside.

Spoon over the onion gravy to finish.

Enjoy!
