Preheat the oven to 200°C. Line two baking trays with baking paper. Place chicken tenders on a prepared tray and cook for approximately 20–25 minutes, turning once.

Lay Bürgen slices on a tray, drizzle with oil and top with cheese.

At the 20 minute mark add the second tray with bread to the oven and cook for 5 minutes with the tenders.

Slice chicken on a chopping board.

To make the open sandwiches, top each slice of Bürgen with mayonnaise, relish, shredded iceberg, diced cucumber and tomatoes, chicken tenders, and a sprinkle of micro radish.
