Place 4 large eggs in a small saucepan; add water to cover eggs by 1 inch. Bring to a boil. Remove pan from heat; cover, and let stand 13 minutes. Drain; rinse eggs under cold water. Peel eggs; halve lengthwise. Remove yolks leaving whites intact; place yolks in a medium bowl.
Add 2 tablespoons reduced-fat mayonnaise, 1/2 teaspoon each Dijon mustard and white-wine vinegar, and a dash of hot sauce; season with coarse salt and ground pepper. Mash together with a fork until combined.
Spoon filling into egg whites; sprinkle with thinly sliced scallions or paprika.
