Savory Spinach Balls

This is a handy make-ahead appetizer. Prepare a batch, freeze the unbaked balls, and then bake as many as you need later.

2 packages frozen chopped spinach, cooked and drained
1 large onion, chopped fine
4 eggs, beaten
3/4 cup butter
1/2 teaspoon salt
1/2 teaspoon garlic salt
1/2 teaspoon thyme
1/2 cup Parmesan cheese
2 cups stuffing mix

Mix all ingredients in a large bowl; chill 1/2 hour.

Preheat oven to 350 degrees F. Grease cookie sheets or line with parchment paper.

Roll spinach mixture into small balls (rounded teaspoons or tablespoons). Bake 15 minutes.
