Preheat the oven to 375°F (190°C).

Place the ready-made pie crust in a 9-inch pie dish and press it firmly against the bottom and sides.

In a large mixing bowl, combine the roasted pumpkin puree, crumbled goat cheese, and chopped spinach.

In a separate bowl, whisk together the eggs, heavy cream, salt, black pepper, and nutmeg.

Pour the egg mixture over the pumpkin, cheese, and spinach mixture. Stir well to combine.

Carefully pour the filling into the prepared pie crust.

Place the quiche in the preheated oven and bake for about 40-45 minutes, or until the filling is set and the top is golden brown.

Once cooked, remove the quiche from the oven and let it cool for a few minutes before slicing and serving.
