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

Chop the potatoes lengthways into 1cm slices, then chop into 1cm wide chips (no need to peel).

Pop the chips 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, 25-30 mins. Turn halfway through.

Meanwhile, put the rogan josh curry paste and breadcrumbs into a large bowl, then mix to combine. Add the lamb mince.

Season with the salt for the burgers (see pantry for amount) and pepper, then mix with your hands. 

Roll the mince 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 mince.

Pop the burgers onto a lightly oiled baking tray.

When the fries have 15 mins left, bake the burgers on the middle shelf of your oven until cooked through, 12-15 mins. IMPORTANT: The burgers are cooked when no longer pink in the middle.

Meanwhile, zest and halve the lemon (see ingredients for amount).

Trim the cucumber, then quarter lengthways. Chop widthways into small pieces. Cut the tomato into 1cm chunks.

Squeeze the lemon juice (see ingredients for amont) into a large bowl. Mix in the sugar and olive oil for the dressing (see pantry for both amounts) and season with salt and pepper.

Add the cucumber and tomato to the dressing and toss together.

Halve the burger buns and pop them into the oven to warm through, 2-3 mins. 

Meanwhile, in a small bowl, mix the mayo (see pantry) and mango chutney. Taste and season with salt and pepper if needed.

Once the fries are cooked, sprinkle over the lemon zest and toss to evenly coat. 

When everything's ready, spread half the mango chutney mayo over the bun bases. Top with the lamb burgers, then sandwich shut with the bun lids.

Serve your burgers with the zesty fries alongside.

Serve the salad alongside the burgers, with the rest of the chutney mayo on the side for dipping.
