This is less of a recipe and more an assembly sandwich but it truly is a great one.
Grill the bacon on a baking tray on a wire rack for maximum crisp. Timing will vary but cook at medium-high and keep an eye on it.Add the shredded chicken to a bowl, then add the mayo, Dijon, spring onion, chives and salt and pepper. Mix together, taste and adjust seasoning if needed.
Slice the bread in half (chop off the ends if you like and you can use those for croutons!) and then spread with pesto on both sides. Layer on curls of prosciutto (not flat) then top with the chicken mayo mix. Add crispy bacon, avo slices, parmesan shavings, rocket and drizzle with balsamic glaze. Then add a good handful of crisps and close with the other of bread. Press gently and then slice in half. Enjoy!
