Preheat the oven to 210°C. Peel or thoroughly wash the potatoes and then cut into fries of no more than 1cm thickness.

Transfer to a bowl and drizzle with the olive oil (see Tip). Season the fries with salt and pepper, then toss well to coat. Transfer to a parchment-lined baking sheet and bake in the oven for 30 - 40 minutes or until golden-brown, tossing halfway.
Tip: to save time washing up, you can also transfer the fries directly to the parchment-lined baking sheet.

Meanwhile, slice the onion into half rings. Heat a clean frying pan over medium-high heat and fry the onion with a pinch of salt. After around 6 - 8 minutes or when the onion darkens, add half of the butter. Fry for 3 - 4 more minutes, stirring regularly. Deglaze with the water and half each of the sugar and balsamic vinegar (see pantry for amounts). Fry for 2 - 3 more minutes and then keep warm until serving.

When the fries have 10 minutes left, melt the rest of the butter in a frying pan over medium-high heat. Fry the burger for 5 minutes, then flip and top with the blue cheese. Cover with the lid and fry for another 5 minutes, then turn off the heat and set aside, still covered.

Cut open the burger bun and heat in the oven for 2 - 3 minutes. Dice the tomato. In a salad bowl, combine the rest of the balsamic vinegar with the sugar, along with some extra virgin olive oil as preferred. Season to taste with salt and pepper. Add the arugula and the tomato, then toss well to combine with the vinaigrette.

Spread the burger bun with some mayonnaise as preferred, then top with the burger, the caramelised onion and some of the salad. Serve with the fries, the rest of the salad and some mayonnaise as preferred.
