I don't like lamb so I don't make shepherd's pie very often ... but with beef (cottage pie) ... yupper! Dominick's (Safeway) supermarket carries a good frozen one under the Dominick's name- black box, yellow letters. I love cottage pie. I'll have to try doing it with ground turkey, never thought of that.

Here's one for meat pies. I learned about meat pies from the Frugal Gourmet. This recipe is called Armenian meat pies - I don't know anyone Armenian, though! I stink at making dough so I use a bought pie crust instead.

There's a restaurant near my house that serves authentic British pub grub. I have a serious shepherd's pie craving coming on!
