I found a boneless turkey breast at New Seasons in their freezer and it worked perfectly, but chicken would be fine too. Needed a bit more salt IMO but otherwise the flavors were great and the turkey came out tender. I did not make the biscuits to save on time and just purchased some Pillsbury biscuits to bake before serving. Will make again and it made so much, I was able to freeze half for another meal.
I didn't make the biscuits because I already had made some dinner rolls.
Here are some changes I made:
I used boneless, skinless chicken breast and thighs because there weren't any small turkey breasts at the store. I also used whole wheat pastry flour in place of the white whole-wheat flour. I added the flour to the cooked vegetables and cooked the flour until it was absorbed and then added the chicken stock.
We really enjoyed the taste and will definitely make this again. This is suppose to be a stew, but it's more like a "stoup" (sort of stew, sort of soup). This is a nice weeknight dinner because you can make it under an hour.
