Preheat the air fryer to 200ºC.
Remove all inner packaging from the cheese.
Slice the cheese, in half.
In a small bowl, combine the mascarpone, pesto.
Spoon the mixture on one half of the cheese and place the second piece of cheese over to create a sandwich.
Carefully toss the cheese in flour, then in the beaten egg then in the breadcrumb to create a light crust all around.
Place in in a small ovenproof ceramic dish to fit the cheese. Sprinkle black pepper and salt.
Bake in the air fryer oven for 10-15 minutes or so, until the cheese is warmed and melted in the center.
Cut into the cheese and peel back the rind, dip in the bread and crackers. Serve with some onion relish.
Enjoy while piping hot.
