Prepare the Spinach: Blanch the spinach in boiling water for about 2 minutes until wilted. Drain and chop finely.
Mix the Filling: In a large bowl, combine the crab meat, softened cream cheese, chopped green onions, and the prepared spinach. Season generously with salt.
Prepare the Egg Rolls: Lay an egg roll wrapper on a flat surface, and spoon about 2 tablespoons of the filling into the center. Moisten the edges with water, then fold the bottom over the filling, fold in the sides, and roll tightly.
Fry the Egg Rolls: Heat oil in a deep frying pan over medium-high heat. Fry the egg rolls in batches until golden brown and crispy, about 3-4 minutes per side. Drain on paper towels.
Serve: Allow to cool slightly before serving with your favorite dipping sauce.
