Instructions

1

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.

2

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.

3

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

Thinly slice the remaining baby gem.

Halve the baby plum tomatoes. 

4

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.

5

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.

6

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 and tomatoes to the remaining pickled onion with a drizzle of oil and toss to coat.

Serve the salad and chips alongside your veggie burgers.

Enjoy!
