My spin on Shepherd's Pie

So I don't use ground beef for my Shepherd's Pie. Chicken and mushrooms, in white sauce, are way more tempting [the green is from bell peppers that I threw in on a whim] =D This is what the mixture looks like before the mashed potato covering. Just to give you an idea of the consistency of the mixture.

I don't use an exact recipe, so I won't be able to give you one. But I'll up the general instructions soon!
