Turkey Shepherd's Pie

My husband has been asking me to try a Shepherd's Pie. Neither of us have had this particular concoction to my knowledge though I have no idea why. Just not something either of our families made. I caught an episode of Ellie Krieger on the Cooking Channel and she happened to be making a Healthy version of the Shepherd's Pie. I thought to myself (imagine a quizzical look and a thought bubble here) "Self, that's an easy recipe, and healthy to boot. I could do that!" So here we go. I changed it up even more from Ellie as I wanted to use my thawed ground turkey. It's not bad with the turkey but the onion overpowers the turkey so I think they red meats may have been a better option unless you cut the onion down.
(Possibly the worst picture I've ever posted but i was trying to show the inside and got in a hurry)
