Preheat your oven to the temperature indicated on the pie crust packaging.
Line the chilled pie crust with parchment paper or aluminum foil and fill it with pie weights, uncooked rice, or dried beans for blind baking.
Bake the crust for about 10-15 minutes until it turns light golden brown.
Remove the parchment paper or foil and weights, then return the crust to the oven for a few more minutes to fully bake and become crisp.
In a bowl, whisk together eggs, milk, nutmeg, hot sauce, salt, and pepper until well combined.
Spread the spinach, ham, and cheese evenly over the prebaked crust.
Pour the egg mixture over the filling in the crust.
Bake the quiche in the preheated oven at 375°F (190°C) for 40-50 minutes or until a knife inserted in the center comes out clean.
Allow the quiche to rest for 5-10 minutes before slicing and serving.
