Chipotle Turkey Burger With Caramelised Onions

Preheat the oven to 220°C/ 200°C (fan)/ gas 7

Cut the potatoes (skins on) into chips

Add the chips to a baking tray with a drizzle of vegetable oil and a pinch of salt and pepper

Give everything a good mix up and put the tray in the oven for 20-25 min or until the chips are golden and crisp

While the chips are cooking, peel and finely slice the red onions

Heat a large, wide-based pan (preferably non-stick) with a drizzle of olive oil over a medium heat

Once hot, add the sliced onions with a pinch of salt and sugar

Reduce the heat to very low and cook the onions, stirring frequently, until ready to serve or until they have softened and caramelised

Meanwhile, season the turkey mince with a generous pinch of salt and pepper

Massage the meat with clean hands for 1 min (this helps them to hold their shape whilst cooking)

Divide the mince into 2 [4], shape them into patties and refrigerate until later

Slice the brioche buns in half

Heat a separate, large, dry, wide-based pan (preferably non-stick) over a medium heat and add the brioche halves, cut-side down, and cook for 2-3 min or until toasted

Reserve the pan

Combine the mayo with the chipotle paste (can't handle the heat? Go easy!) in a small bowl and season with salt and pepper – this is your chipotle mayo

Wash the gem lettuce[s] and pat dry with kitchen paper

Remove 2[4] whole outer leaves and set aside for serving and tear the remaining leaves into bite-sized pieces

Add the torn leaves to a bowl and mix with a drizzle of olive oil and season lightly with salt and pepper – this is your crisp lettuce salad

Return the reserved pan to a medium heat with a drizzle of vegetable oil

Once hot, add the chilled patties and cook them for 3-4 min on each side or until they're cooked through

Tip: Keep pressing the patties down with a spatula to keep them flat
