Chip, Chip, Hooray

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, bake on the top shelf until golden, 25-30 mins. Turn halfway through.

Pickle the Onion

Meanwhile, halve, peel and thinly slice the red onion.

In a medium bowl, combine the red wine vinegar, sugar (see pantry for amount) and a pinch of salt and pepper.

Add half the onion, toss to coat, then set aside to pickle.

Finish the Prep

Trim the baby gem and halve lengthways. Tear off two leaves per person and set aside.

Thinly slice the remaining baby gem.

Make your Relish

Pop a large frying pan on medium heat with a drizzle of oil.

Once hot, add the remaining onion to the pan and cook until softened, 4-5 mins. Season with salt and pepper.

Add the balsamic vinegar and cook until evaporated, 1 min.

Stir in the red pepper chilli jelly and cook until sticky, 1-2 mins. Transfer to a small bowl and set aside.

Fry the Burgers

When the chips have 10 mins remaining, wipe out the (now empty) pan and return to medium-high heat with a drizzle of oil.

Once hot, fry the burgers until browned, 3-4 mins on each side.

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

Stack up and Serve

When everything's ready, spread the mayo (see pantry for amount) over the bun bases. Top the bases with the veggie burgers, onion relish, reserved lettuce leaves and a few slices of pickled onion, then sandwich shut with the bun lids.

Add the sliced baby gem to the remaining pickled onion with a drizzle of oil and toss to coat.

Serve the salad and chips alongside your veggie burgers.
