Add spinach one handful at a time, allowing the spinach to wilt before adding in more.
Add in the crushed red pepper, seasoning, salt and pepper.
Continue to cook, stirring often to ensure most of the liquid from the spinach evaporates.
Add in the chopped artichokes, reduce the heat to low and begin adding in the cream cheese and mozzarella.
Stir the mixture until all the cheese has melted.
Next, stir in the sour cream and Pecorino Romano
Eat right away or transfer the dip into an oven proof serving bowl or skillet and place in the broiler for 5-8 minutes until the top gets nice and crispy.
