ThePaleoMom: Recipe: Tourtière-Inspired Shepherd’s Pie---I made this last night with deer hamburger. It was really good and the family loved. I made the following changes: added carrots, did NOT add mushrooms, used tapioca starch instead of arrowroot, pinch of cloves and allspice, and about 1 tsp thyme. I recommend using two heads of cauliflower as my top layer was thin. Had a great flavor.
