Slimming World Chicken and Mushroom Pie – Half Syn

Winter warming goodness with only half a syn

I was looking through many of my slimming world resources this week looking for something to make with Chicken Fillets. Earlier in the week I been to the local butcher group and bought a ton of fillets.  Most of the recipes I had come across had already been made and, I was looking for something new to add to the site. After a while, I stumbled across this recipe for Chicken and Mushroom pie and thought I would give it a go.

It was a success in the household. I thought I would try it out with the hoard of kids that we seemed to have over that evening. We had clear plates everywhere. Well, apart from a couple of bits of leek that had picked out. I consider that a success!

Made with a mash lid, no syns there

As flour is a forbidden fruit in Slimming World (well, it’s high in syns) we can’t use regular pastry for a lid on our pie. This recipe uses mashed potato with a little stock for a lid. In doing this, the syns are kept to a bare minimum. In fact, the half syn that the recipe carries is from the use of gravy granules. Gravy granules are necessary though, to thicken the sauce a little.
