1Place eggs in single layer in 2-quart saucepan. Cover with cold water at least 1 inch above eggs. Cover saucepan; heat to boiling. Remove from heat; let stand covered 15 minutes. Drain. Immediately place eggs in cold water with ice cubes or run cold water over eggs until completely cooled.
2To peel, gently tap each egg on countertop until entire shell is finely crackled. Roll gently between hands to loosen shell. Starting at large end, peel egg under cold water to help remove shell.
3In medium bowl, chop eggs with knife or pastry blender. Add mayonnaise, curry powder, salt and pepper; mix with fork until blended. Spoon egg salad into endive leaves; sprinkle with onion.
