Spinach Parmesan Balls

Why I Love This Recipe
I found and adapted this recipe from one featured on "Party Line with the Hearty Boys," a Food Network show. This is a big hit at parties, and so simple to make! The fact that it's vegetarian is nice, also: a lot of my friends are vegetarians. I almost always get asked for this recipe when I bring these to a gathering.
Ingredients You'll Need
2 10-oz packages frozen chopped spinach, thawed
5 eggs
2 small onions, minced
10 TBSP butter, softened to room temperature
1 1/2 cups shredded Parmesan
2 garlic cloves, minced
1/4 teaspoon dried thyme
1/2 teaspoon ground cayenne pepper
1 3/4 cups Italian-style bread crumbs
Reynolds Parchment Paper
Directions
Preheat the oven to 350˚ F.
Squeeze the excess water from the spinach by wrapping it in an old towel (or a couple of heavy-duty paper towels will work), then put it in a large mixing bowl.
Add the remaining ingredients and mix well by hand (this part is fun! I think it feels really nice to get your hands in all that goo. But be sure to wash your hands well afterward).
Form the mixture into bite-size balls (about 1-inch diameter), either by hand or with a small ice cream scoop or melon baller. Place the balls closely together on a baking sheet lined with Reynolds Parchment Paper for easy cleanup.
Bake in the top half of the oven until firm to the touch, about 20 to 25 minutes. Let cool 5 minutes, and then transfer to a platter. Serve immediately.
If taking to a party, I usually reheat them in the host's oven for 10 minutes before serving.
