I Want A Recipe: Shepherd's Pie

I Want a Recipe: Shepherd's Pie

My MIL is coming to town this Thursday and she is what I will kindly refer to as PICKY when it comes to food. She doesn't like a lot of seasoning, is pretty traditional about foods, and after endless tours of restaurants, we've managed to find 2 places that she likes.  Wait.  3.  One of which is Arby's!  So I'm pretty sure that shouldn't count.

Anyway, I'm hoping to make a Shepherd's Pie Thursday night.  My plan is to use instant mashed potatoes so that John will actually eat it and that will cut a lot of the prep time down.

If you have a great recipe, could you post it?
