Stir-Fried Egg and Tomato

Beat eggs with 1/2 teaspoon salt until smooth but not frothy. Heat 1 tablespoon oil in a 12-inch nonstick skillet over medium-high heat until hot. Add eggs and cook, undisturbed, just until a thin film of cooked egg forms on bottom of skillet but most of eggs are still runny, 5 to 10 seconds. Immediately scrape eggs into a bowl. Wipe out skillet. Heat remaining tablespoon oil in skillet over medium-high heat until hot. Add scallions and stir-fry until just softened, about 30 seconds. Add tomatoes and cook, stirring and turning occasionally, until juices are released and tomatoes are slightly wilted but still intact, 4 to 6 minutes. Sprinkle sugar and 1/4 teaspoon salt over tomatoes and stir to combine. Return eggs to skillet and cook, stirring occasionally, until eggs are just cooked through. Serve sprinkled with reserved scallion greens.
