Preheat the broiler. Cut each slice of bread in half diagonally and arrange on a large baking sheet. In a blender or food processor, combine the shrimp, egg white, ginger, garlic, salt, and pepper. Process until smooth, scraping down the sides of the container as necessary. Transfer to a medium bowl and stir in the scallions. Spread on the bread and broil 4 inches from the heat for 3 minutes on until golden brown. Serves 4.  |
