Make the spice mix by mixing together the 1 ½ teaspoons smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon dried oregano, ½ teaspoon salt and ¼ teaspoon black pepper in a small bowl and set aside.
Wash and cut the 2-3 medium potatoes into chips, then pat them dry with paper towel.
Place the chips in a large mixing bowl with 1 tablespoons olive oil and sprinkle in half of the spice mix. Toss well to coat the potatoes thoroughly.
Arrange the potatoes on a baking tray and bake in a preheated oven at 200°C/400°F for 30–40 minutes, or air fry for about 20 minutes, until golden and crispy.
While the potatoes are cooking, heat the remaining 1 tablespoons olive oil in a frying pan over high heat. Add the 500 grams lean beef mince/ground beef, 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, make the burger sauce by combining the 4 tablespoons mayonnaise, 1 tablespoon ketchup, 1 teaspoon mustard, 1 teaspoon pickle juice, ½ teaspoon garlic powder, ½ teaspoon smoked paprika. Taste and adjust the seasoning if needed.
Once the potatoes are ready, divide them among your bowls. Fill the remaining space with shredded iceberg lettuce, then add the beef mince, cheese and pickle slices.
Drizzle the burger sauce over the top and serve.
