Sam's has discontinued them, but the July 2013 issue of Bon Appetit magazine has a recipe for turkey burgers that's very similar to the spinach and feta cheese chicken burgers.  I substituted chicken for turkey and it's very easy to make.  Mix:

1 lb. ground turkey or chicken
4 cups finely chopped spinach, stems removed
4 scallions thinly sliced
3/4 tsp. each of cumin, kosher salt and pepper.

Mix together, form patties and fry or grill them to your liking.  We added some sauteed mushrooms and swiss cheese on the top.  Delicious!
