Slice the acorn squashes in half and lay out onto a baking sheet with a thin layer of water in the bottom.
Place the baking sheet into the oven and bake for 20-30 minutes until the squashes have softened.
Meanwhile, sauté the ground turkey and fennel with a teaspoon of salt until the turkey has browned and the fennel has softened.
When the squashes are cooked, remove them from the oven and flip them over.
Add the fresh herbs and walnuts to the turkey and fennel and mix well.
Stuff the squash cavity with the turkey filling (see notes below) and place back into the oven for an additional 20 minutes.
Remove from the oven and allow to cool. These taste great with a little sour cream on top!
Notes
Optional: You can melt parmesan cheese over the stuffed squash. Once the squashes are stuffed, sprinkle the parmesan cheese on top and place in the oven for 20 minutes.
