treasure chests, quite simple.
roll out the pastry and cut into the required number of squares ( i our house its 2 big ones and 2 smaller ones!). just inside the square score but don't cut threw the pastry. cook according to instructions, the stuff i but is 20 mins at 180C.
whilst pastry is cooking, fry and onion and the chicken (diced), add garlic/herbs of choice, once chicken cooked add mushrooms and sweetcorn, leave to cook. in sep sauce pan make a white sauce (250ml milk, 25g flour, 25g marg, melt marg add flour cook for couple of milk, slowly add milk a little at a time, lots of stirring)
add white sauce to chicken ( i ignore the lumps in my sauce!)
remove pastry cases from oven, the scored but should now come of the top leaving a chest, place teh chicken mixture into the hoel and replace the top, there you have treasure chests! we replace the chicken with tuna and prawns for seafood treasure chest!
