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

Cut the potatoes lengthways into 1cm slices, then cut into 1cm wide fries (no need to peel). 

Pop the fries 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 the chips on the middle shelf until golden, 25-30 mins. Turn halfway through. 

Meanwhile, drain the sweetcorn in a sieve. Halve the avocado and remove the stone. Use a tablespoon to scoop the flesh out onto a board. Cut into 1cm chunks.

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

Add the sweetcorn and avocado to the dressing and mix together. Set aside.

Sandwich each chicken breast between two pieces of baking paper or cling film. Pop onto a board, then bash with the bottom of a saucepan until it’s 1-2cm thick. 

Sprinkle the Cajun spice mix over both sides of the chicken and season with salt and pepper. IMPORTANT: Wash your hands and equipment after handling raw chicken and its packaging.

Crack the egg (see pantry for amount) into a bowl and whisk.

Put the breadcrumbs into another bowl and season with the salt (see pantry for amount) and pepper.

Dip the chicken into the egg and then the breadcrumbs, ensuring it's completely coated. Transfer to a clean plate. IMPORTANT: Discard any excess egg. 

Pop a large frying pan on high heat and add enough oil to completely coat the bottom of the pan. TIP: You want the oil to be hot so the chicken fries properly - heat for 2-3 mins before you add the chicken.

Once the oil is hot, carefully lay the chicken into the pan and fry until golden brown, 2-3 mins on each side. Adjust the heat if necessary.

Transfer the chicken to a baking tray and bake on the middle shelf of your oven until cooked through, 8-10 mins. IMPORTANT: The chicken is cooked when no longer pink in the middle.

Meanwhile, grate the cheese. Halve the burger buns and sprinkle the cheese onto the bun bases. Just before serving, pop them into the oven until melted, 2-3 mins. 

When ready, transfer the buns to your plates.

Top the cheesy bases with a piece of fried chicken and a handful of rocket. Spread the burger sauce over the bun lids and sandwich together. 

Serve with the avocado and corn salsa and fries alongside.
