Preheat the oven or air fryer to 200°C (390°F). Line a baking tray with parchment paper.
In a bowl, add all of the chicken ingredients, except the oil and BBQ sauce, and mix to combine.
In a separate bowl, add all the potato ingredients and combine.
Spread the potatoes onto the lined baking tray and bake for 25–30 minutes, or until golden and crispy. For the air fryer, cook for 20–22 minutes.
Add the olive oil to a pan over high heat and sear the chicken for 5–6 minutes, or until cooked through and the internal temperature reaches 74°C (165°F). Work in batches if needed. Add the BBQ sauce and mix well. Cook for a further minute.
Add the cooked potatoes to the pan and mix to combine. Sprinkle over the cheese, cover with a lid, and let melt for 1–2 minutes. Remove from the heat.
Portion into 5 x 750ml meal prep containers. Garnish with a drizzle of your favourite sauce and flat-leaf parsley.
