Preheat oven to 450 degrees
Line a baking sheet with foil or parchment + spray with olive oil to prevent squash from sticking
Slice acorn squash in half, scoop out seeds and place flat on sheet sprayed with olive oil.
Bake the squash for 20 minutes, until it is tender when pierced with a fork
While the squash cooks - heat 1 tablespoon of olive oil in a pan. Sauté turkey in olive oil for 10-15 minutes until brown.
While the turkey is cooking, chop mushrooms, apples + herbs.
Add in chopped mushrooms, apples, chicken stock, and spices to the pan with the cooked turkey. Sauté for an additional 5 minutes.
When the squash is done, remove from the oven + scoop out most of the cooked center, leaving a little bit of filling in the acorn squash.
Add the squash filling to the turkey/mushroom/apple mixture in the pan+ stir until completely mixed in.
Scoop the turkey/squash mixture back into the squash + top with cheese of choice
Bake them at 450 for 5-10 minutes until cheese melts. Optional: broil for 2-3 minutes so the cheesy gets crispy.
