This reminds me of one of the staple items on display at French boulangeries (in Singapore, we used to have a humongous chain of these which seems to have downsized recently called D***france, mainly due to increasing competition from new upstarts specializing in better quality breads). It’s actually a rather fool-proof recipe using mostly ready-made items available from the supermarket.
100g White mushrooms
3 cloves chopped garlic
2 sheets of filo pastry about 30cm by 30 cm (I used the brand Pampas)
Shredded cheddar cheese
Parsley to sprinkle
Firstly, heat up a pan and saute the garlic in butter. Add the chopped white mushrooms and saute till soft (about 3-4 minutes). Add a dash of black pepper to season. Remove and set aside.
Divide 1 sheet of filo pastry into 4 equally sized squares. Fold one square into 2, sprinkle with a bit of parsley, add the ham and sauteed mushrooms, then sprinkle with cheddar cheese and parsley.
Bake in the oven at 200 degrees celsius for about 20-25 minutes till it turns golden.
