Cook the quinoa according to the package directions.
Meanwhile, heat the oil in a large nonstick skillet over medium heat. Add the eggs and cook, covered, 2 to 4 minutes for slightly runny yolks. Season with ¼ teaspoon each salt and pepper.
Serve the quinoa topped with the fried eggs, avocado, and salmon, dividing evenly. Drizzle with the lemon juice and top with scallions.
