Peel and devein the shrimp.
Marinade the shrimp. Add the sesame oil and salt to the shrimp and mix well. Refrigerate for at least 30 mins to 4 hours.
Cut the scallops lengthwise and refrigerate until ready to use.
Prepare the tofu for steaming. I used a wok and added water, and a trivet. Once the water boils, place the dish with the seafood topped tofu in the wok and close the lid. Steam for 6 minutes on high or until the shrimp turns pink. Remove from heat.
Pour the sauce on top of the tofu. Sprinkle with green onions, drizzle the sesame oil and serve immediately.
