Egg salad on cucumber slices instead of bread. These little bites are a refreshing Monday low carb lunch that's light enough to keep you sharp at work.
Place eggs in a pot of cold water and bring to a boil over medium-high heat. Once boiling, reduce to gentle simmer and cook for 8 minutes for firm yolks.
Transfer eggs immediately to an ice bath or run under cold water to stop cooking. Peel shells once cool and pat eggs dry.
Dice the hard-boiled eggs and celery finely. Slice cucumber into about 16 thick, uniform rounds, roughly 1/4-inch thick each.
In a bowl, mix diced eggs, celery, mayonnaise, Dijon mustard, chives, salt, and pepper. Stir gently to blend without mashing eggs.
Arrange cucumber rounds on a platter. Spoon a generous mound of egg salad onto each round, pressing gently to secure. Serve immediately for crisp texture.
