Place pepperoni slices in a frying pan over medium/high heat and cook until crisp.

Melt butter in a medium saucepan over medium/high heat. Add minced garlic, salt and flour, and cook together for one minute stirring occasionally. Add the cream and whole milk, and cook until the sauce starts to thicken. This should take about five minutes. Take off the heat and add the Parmesan cheese, and whisk until melted. Add in the mozzarella cheese half cup at a time and adding the next half cup once the previous has melted. Sprinkle in the minced parsley. 

Pour into a bowl or carved out bread bowl, and top with crispy pepperoni slices. Serve with bread, naan, bell peppers or any desired veggies.
