Preheat your oven to 220°C/200°C fan/gas mark 7.

Chop the potatoes into 2cm wide wedges (no need to peel). Pop them onto a large baking tray. Drizzle with oil, season with salt and pepper, then toss to coat.

Spread out in a single layer. TIP: Use two baking trays if necessary.

When the oven is hot, roast on the top shelf until golden, 25-35 mins. Turn halfway through.

Meanwhile, pop the sausage meat into a large bowl.

Roll into even-sized balls, then shape into 1cm thick burgers, 1 per person. TIP: The burgers will shrink a little during cooking. IMPORTANT: Wash your hands and equipment after handling raw meat.

Heat a drizzle of oil in a large frying pan on medium-high heat.

Once hot, add the burgers and fry until browned and cooked through, 10-12 mins total. Carefully turn them every 2 mins and lower the heat if needed. IMPORTANT: The burgers are cooked when no longer pink in the middle.

While the burgers cook, grate the cheese.

Pop the onion marmalade into a small bowl and break it up with a spoon.

Cut the tomato into 2cm chunks.

When the burgers are cooked, remove the pan from the heat.

Carefully place the cheese on top of the burgers, followed by a spoonful of the onion marmalade. Cover with a lid (or foil), then set aside, off the heat, to allow the cheese to melt, 3-4 mins.

While the cheese melts, halve the burger buns. Pop them onto a baking tray and into oven to warm through, 2-3 mins.

Meanwhile, in a large bowl, combine the sugar, olive oil for the dressing (see pantry for both amounts) and red wine vinegar. Season with salt, pepper and mix well.

Add the tomatoes and the baby leaves to the dressing and toss to coat.

When everything's ready, pop the burgers into the buns and serve on your plates with the wedges and salad alongside.

Enjoy!
