¼ Mushrooms
3 Tablespoons Soya Sauce
1 Tablespoon Flour
½ Onion
½ Pint Vegetable Stock
Salt & Pepper

Chop the onion finely and fry with mushrooms, soya sauce, salt and pepper until soft.
Add the flour and cook on for 5 minutes.
Add the stock, bring to the boil and then simmer for 10 minutes. 
We usually put everything in to the blender and make it smoother as one of our kids doesn't like chewing mushrooms!
