1. In a medium nonstick skillet or wok set over medium-high heat, add the oil and heat until shimmering, 1 to 2 minutes. Add the eggs to the skillet and stir constantly to scramble the eggs, cooking until the egg whites are set, 2 to 3 minutes.

2. Add the onion and cook, stirring occasionally, until the onion is tender, 3 to 5 minutes. Stir in the cooked rice, crabmeat, salt, garlic powder, white pepper, sugar and soy sauce and mix to combine. Add ¼ cup of the scallions and cook, tossing frequently for about 3 minutes, until the rice and crab are heated through and the sauce is incorporated.

3. Divide the fried rice between serving bowls and sprinkle with the remaining 1 tablespoon of scallions. Serve the fried rice alongside the sliced cucumbers and tomatoes.
