Add light flavored oil to a wok or large frying pan. Pan sear the shrimp over medium high heat on both sides until lightly golden and the shrimp are no longer translucent. (Don't crowd the pan and do not overlap the shrimp. Cook in batches if pan is too small.) Remove shrimp from the pan and keep warm.
If pan is dry, add in another tablespoon of light flavored oil and add in the grated ginger and scallions. Stir fry for 1 minute until aromatic. Toss in the chopped or grated tomatoes for 1 to 2 minutes or until bubbly. (If you want to add any other quick cooking vegetables like spinach, bok choy, thinly sliced cabbage or other, add it now and stir fry for a minute or two, until crisp tender.)
Pour in the beaten egg and tofu mixture into the pan on medium-low heat with the aromatics and tomatoes. Lightly scamble with slow and easy movements until about 50% cooked.
Add in soy sauce, sesame oil and water to the eggs along with the cooked shrimp. Toss lightly until about 75% cooked through with a light ginger scallion sauce. Remove the pan from the heat. The heat from the pan will continue to cook the eggs.
