Cook and stir ham and pepperoni in a skillet over medium heat until lightly browned, about 10 minutes. Drain grease and set ham and pepperoni aside to cool.
Stir ricotta cheese, Romano cheese, eggs, parsley, salt, and black pepper together in a bowl until well mixed. Add ham and pepperoni to the mixture and stir to combine. Pour half the filling into each pie crust.
Bake pies in the preheated oven until filling is set and lightly browned, 35 to 40 minutes.
