Preheat the oven to 350° F.
Rinse and drain the frozen spinach and remove as much water as you can.
In a bowl large enough to hold all the ingredients, combine the spinach, stuffing, Parmesan cheese eggs, butter and salt & pepper.
If you have time, refrigerate the mixture until firm. This will make the next step easier, but it is not necessary especially when you are throwing these together at the last minute.
The recipe says "Make Balls". It doesn't say how large or small these balls should be, just "Make Balls." I guess it depends on how many you going to serve. We made ours on the large size and everyone loved them.
Bake for 10 to 15 minutes until cooked through.
