Preheat the oven to 375°F (190°C).

Place the pre-made pie crust in the pie dish, press it down gently, and poke holes in the bottom with a fork.

In a skillet over medium heat, sauté the chopped spinach until wilted, about 2-3 minutes.

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

Stir in the chopped ham and shredded cheese into the egg mixture.

Gently fold in the sautéed spinach.

Pour the filling into the prepared pie crust.

Bake in the preheated oven for 45 minutes, or until the center is set and the top is lightly golden.

Let the quiche cool slightly before slicing.
