½ teaspoon salt
½ teaspoon black pepper
4 ounces reduced-fat cream cheese, softened

Mix in the softened cream cheese until fully melted and combined.
Transfer the mixture to a lightly greased 9×13-inch baking dish.
Sprinkle the provolone and mozzarella evenly over the top.
Bake for 18–20 minutes, until the cheese is melted and lightly golden.
Let the casserole rest for 5 minutes before serving, then garnish with parsley if desired.

Heat Level: Medium-high for browning; medium for vegetables; bake at 375°F.

Timing: Avoid baking beyond 20 minutes to keep the cheese creamy.
