I saw this made yesterday on my favourite food show Market Kitchen so I went to the site and found it to save here. The recipe calls for "baby" breast fillets which we call Tenderloins in Australia and are that fillet at the back that virtually just falls off. I reckon 4 tenderloins wwould equal one regular sized breast if you can't get them (the tenderloins). It looked so simple to make and would be beautiful for a summer brunch, lunch or picnic.
