I got this recipe off the food network and modified it just a bit. I love these. We served them at our boy's wedding last year.
1 pound package frozen chopped spinach, thawed
1 Tbs. onion powder
10 tablespoons butter, melted
1 cup shredded Parmesan cheese
¼ tsp. garlic powder
1/4 slightly rounded tsp. cayenne pepper*
1 3/4 cups Italian bread crumbs
*Less if the heat bothers you. They aren't hot but they do have just a tiny bit of a bite.
Preheat the oven to 350°
Squeeze excess water from spinach and put in large bowl. Add remaining ingredients and mix well by hand. Form into 1-inch balls. Place the balls closely together on baking sheet. Cook in top half of oven until firm to the touch, about 20 to 25 minutes. Let cool 5 minutes, serve immediately.
