In a large bowl, mix together the ground pork, chopped shrimp, finely chopped shiitake mushrooms, green onions, soy sauce, sesame oil, minced ginger, salt, and pepper until well combined.

Take a wonton wrapper and place a small spoonful of the filling mixture in the center. Be generous but avoid overfilling.

Moisten the edges of the wrapper with water, then fold it over to create a pouch, pinching the edges firmly to seal.

Choose your cooking method: boil for 4-5 minutes, steam for 6-8 minutes, or pan-fry for 3-4 minutes on each side.

Once cooked, plate your wontons warm and enjoy with your favorite dipping sauce.
