Shepherd's Pie is one of my favorite dishes. I used ground lamb meat (look for it near the hamburger meat and they usually have a section of ground lamb, veal, chicken, etc.) I used a bag of frozen mixed veggies (what I had in the freezer).
We all really enjoyed the flavors of this dish. It was VERY flavorful and I think using the lamb and fresh thyme had a lot to do with it. I usually use hamburger meat and it's pretty bland.
I didn't have time to brown the potatoes but we all enjoyed it!
