Shred the chicken as finely as you can. The best method is using a stand-mixer. Just put the meat in the bowl with the paddle attachment and mix on medium speed until it's really finely shredded (~ 1 minute). Else use a handheld beater or your hands.

Mix the Sauce ingredients in a bowl until smooth - use a whisk if needed.

Pour Sauce over the chicken. Add remaining Filling ingredients. Stir until combined.

Spread bread with butter. Spread with Filling (see below for amount).

Remove crusts if desired (for the authentic "gourmet" experience!) and cut in half. (Tip: For really neat cuts, refrigerate sandwiches before slicing so Filling firms up).

Serve on platters littered with green fluffage, if desired!

Chicken filling per sandwich:- Deli standard (recommended): 100g / 1/2 cup (makes 10 sandwiches)- Very generous: 130g / 1/2 cup (makes 8)- Everyday lunchbox: 80g (1/3 cup) (makes 15).
