Mix together the spice mix ingredients in a small bowl and set aside.

Wash and cut the potatoes into chips, then pat them dry with paper towels. Place the chips in a large mixing bowl with 1 tablespoon of olive oil and sprinkle in half of the spice mix. Mix well to ensure the potatoes are thoroughly coated.

Arrange the potatoes on a baking tray and cook in a preheated oven at 200°C (390°F) for 30–40 minutes, or in the air fryer for about 20 minutes, until golden and crispy.

While the potatoes are cooking, heat the remaining olive oil in a frying pan over high heat. Add the beef mince, breaking it apart with a wooden spoon. Once browned, sprinkle in the remaining spice mix and continue cooking until the meat is darkened and any excess moisture has evaporated.

In a small bowl, combine the burger sauce ingredients. Taste and adjust seasoning if needed.

Once the potatoes are ready, divide them among your bowls. Fill the remaining space in each bowl with shredded lettuce, then add the cooked beef mince, cheese, and pickles. Drizzle the burger sauce over the top and serve.
