Heat the air-fryer or oven to 220C/200C/gas 7. Put the potatoes in the air-fryer or oven, drizzle over 1 tbsp of the vegetable oil, 1 tbsp of the Cajun spice mix, the garlic granules (if using) and season. Cook for 20 mins, shaking halfway, or until crisp and cooked through.

When the potatoes have about 10 mins to go, heat the remaining 1 tbsp oil in a frying pan over a medium-high heat. Once shimmering, tip the mince into the pan, and use a spatula to break it up. Sprinkle over the remaining 1 tbsp Cajun spice mix and season. Cook for 7-8 mins, or until crisp and cooked through.

Divide the potatoes between four bowls, then top with pickles, lettuce, red onion, cherry tomatoes, mince and a little cheese.

Mix the ketchup, mayo, mustard and pickle brine in a small bowl, then drizzle over the burger bowls and tuck in.
