Vol-au-vent with mushroom ragout

Traditional appetizer for Christmas brunch or dinner, but very tasty any time of year.
Make your own ragout from cupboard ingredients and the possibilities are endless!

What you need (4 servings):
4 vegan pastry cases
50g vegan margarine
50g all-purpose flour
500ml mushroom stock (from a stock cube)
100g sliced mushroom (fresh or canned & drained)
1 clove of garlic, minced
salt & pepper to taste
1 tbsp of dried parsley
curry powder to taste (optional)
sambal oelek to taste (optional)
oil

Heat a bit of oil in a skillet. Saute the garlic and sambal oelek for a few minutes. Add the mushrooms and cook until the mushrooms are browned.
In a saucepan, melt the margarine at a low heat, making sure it doesn´t brown. Once it is melted, stir in the flour, about a tablespoon at a time until well incorporated. Cook the sauce on a low heat for a few minutes, stirring continuously. Add a bit of stock to the mixture, stirring well to incorporate the liquid. Add more stock once all the liquid has been incorporated. Continue adding stock until the sauce has the desired consistency.
Stir in the sauteed mushrooms and parsley, and season to taste with salt, pepper and curry powder (note: be conservative with adding extra salt since the stock already contained salt).
Heat the pastry cases in an oven according to the directions on the box (approx. 10-15 minutes at 150°C). Spoon in the mushroom sauce and serve immediately.
