In a large bowl, mix together the zucchini, onion, eggs, Romano cheese, milk, and flour. Season with salt, pepper, garlic powder, onion powder, and parsley.
Heat about 1 tablespoon of shortening in a large skillet over medium heat. Drop 1/4 cupfuls of the batter into the skillet, and flatten slightly with the back of a spatula. Turn fritters over when the center appears dry. Cook on the other side until golden brown. Set aside and keep warm. Add more shortening to skillet as needed, and continue with remaining batter.
