Savoury Mushroom-Cheese Strudel

I improvised this recipe the other day when I defrosted a sheet of puff pastry meaning to make a quiche, then realizing too late I only had 1 egg left. :-( Thank god puff pastry is so versatile, and I jumped on the opportunity to use up some left over mushrooms and brie still left in the fridge. This turned out to be a yummy hit, and it will surely turn into a proper repartoire when an occasion calls for a quick snack or a hors d'oeuvres!!


Savoury mushroom-cheese strudel

Ingredients
250g mushrooms, thinly sliced
1/2 onion, thinly sliced
1 large clove of garlic, finely chopped
2 slices of speck or english style bacon (optional)
dash of herbs provençal
butter, just enough to sautè the above items
1/2 tsp granulated (powdered) vegetable bouillon
dash of pepper
150g brie, chopped (or your choice of cheese)
generous handful of parsley, chopped
1 sheet of puff pastry (about 300g)

Melt the butter in a skillet and prepare the sautè mixture, starting with onion.
When onion starts to soften, add mushrooms, garlic, speck/bacon, and the seasonings. Continue to cook on high heat stirring well, until onions and mushrooms are completely tender.
Just before turning off the heat, add the parsley.
Let it stand to chill to the room temperature.*
(*if the mixture is too warm it will soften the pastry dough immediately, and it will be difficult to flip over in the process.)
Roll out the puff pastry dough, flatten it to about 3mm thickness if the sheet is thicker, spread it flat on a baking sheet.
Mix in chopped brie into the sautèed mixture, blend in evenly.
Arrange the filling on the surface of the pastry sheet across the centre, about 6-7 wide, leaving about 2cm each on both sides (so it can be secured).
Fold the pastry sheet in 3, folding over the both sides together, overlapping slightly at the centre.
Carefully flip over the strudel, so the seam side will be at the bottom. Press the opening edges on both sides gently with a fork to secure them.
Make a few diagonal slits on the surface with a sharp knife.
Bake the strudel in the oven at 200°C for about 10 minutes, or until the surface is thoroughly golden brown.
Let is stand to cool slightly to stabilize the texture before slicing up.
