In a frying pan add the butter and mushrooms. Chop the chicken thighs to bite size chunks and add them to the pan. Add the thyme.

In a separate pan make the bechamel up. Don't forget to season it with black pepper and a dash of nutmeg. Stir in the chicken gravy granules. Pour in the chicken and mushrooms pan as well as the chopped gammon chunks and stir together.

If you need a really substantial pie filling you could add some diced carrot or some frozen peas to the pie filling to bulk it out.

Assemble the pie and glaze it with a beaten egg. Sometimes I let my youngest make some pie decorations with pastry trimmings. My pie dish works better for me if I use a pie whistle to support the centre, as well as making steam holes in the top.

Bake off in the oven for 35 is minutes (when the pastry has come to look golden brown). Take it out of the oven and let it cool for 5 mins before you serve. I put this with mash and some vegetables such as sweetheart cabbage.
