Fish Finger Grilled Cheese Sandwich

1. Preheat the oven or air fryer to 200 ºC. Lay frozen fish fingers onto a baking tray or into the air fryer basket. Cook for approximately 15 minutes until golden and crunchy. 
2. Remove fish fingers from the oven and allow to cool slightly.
3. Turn the oven down to 50 ºC (this will be to keep the sandwiches warm).
4. Lay 8 slices of bread out and butter four of the slices – these will be the bottoms.
5. Spread a layer of mayonnaise on the remaining four sides and sprinkle with chopped chives. 
6. Add a layer of mozzarella to the 4 buttered slices and then add baked fish fingers (4 on each). Top with the cheddar cheese and season.
7. Top the sandwiches with the second slice of bread and butter the tops.  
8. Set a large frying pan over medium heat. Add a knob of butter to the pan and allow it to melt.  Carefully place a sandwich, unbuttered side down, into the pan (you can do two at a time in the pan if you have space). Cook the sandwiches slowly to allow the bread to crisp up and the cheese to melt on the inside.
9. Carefully flip the sandwiches using a spatula and crisp up the other side; once cooked, place into the oven to keep warm. Repeat with the other two sandwiches. When all four are ready, slice and serve.
