Basically it's chicken, penne pasta, cream, mushrooms and tomatoes.

So how would you go about making it but with lovely home ingredients? it's the "creamy tomato sauce" bit I haven't done before, I assume I can just cook the pasta/chicken/mushrooms separately and then heat it all for about twenty mins in the oven in a dish?

Oh poo... Ah well in that case just give me a recipe involving chicken, tinned tomatoes, mushrooms, penne pasta and creme fraiche

That sounds about right I'm getting hungry already
