Finding a recipe

I went to food, nutrition and recipes and typed "chicken casserole" (in quotes so the words won't get separated) and this came up
http://www.diabetes.co.uk/forum/threads/scandis-recipes.55882/#post-519604
There's a casserole there if you scroll down a bit.
I would go easy on the white wine and I don't thicken with flour. Sometimes I take the meat out of the casserole and reduce the liquid by boiling.
Hope this helps.

I think it's easier to search on Google
