Preheat the oven to 425F/220C. Line 2 baking sheets with aluminum foil and lightly coat them with non-stick spray.
In a bowl, mix imitation crab, cream cheese, green onions, soy sauce, salt and pepper until fully combined.
Put 1 tsp in the center of each wonton wrapper. Moisten the edges with the beaten egg.
Bring the sides up together and make a crown.
Place all the crab rangoons on the baking sheets and lightly spray with cooking spray.
Bake in the oven for 12 minutes until the edges are lightly brown.
