Into a Dutch oven, pour oil to a depth of 2 inches. Heat to 360°.

In a large bowl, combine cornmeal, flour, pecans, green onions, sweet potatoes, egg, milk, and salt; stir until all ingredients are moistened.

Drop batter by rounded tablespoonfuls into hot oil in batches. Cook each batch until golden brown, 2 to 3 minutes on each side. Drain on a wire rack over paper towels. Serve immediately.
