Grate the squash and place it in a large bowl. Stir in the diced pecans and onion.
In a separate bowl, mix together the eggs, flour, and salt. Pour the egg mixture over the squash mixture, and stir to combine.
Heat the oil in a large skillet over medium heat. Using a 3 tablespoon scoop (such as an ice cream scoop), place the fritters into the hot pan and press gently to form a patty. Cook for 3 minutes on each side, or until lightly browned. Repeat with the remaining batter. (Yields 12 fritters)
