Egg Salad Sandwich with Radishes and Watercress

Ingredients

10 large organic eggs 2½ tablespoons mayonnaise 2½ tablespoons organic plain low-fat yogurt 1½ tablespoons lemon juice 1 tablespoon Dijon mustard Salt and pepper 3 scallions, sliced thin12 slices hearty 100 percent whole-grain sandwich bread 6 radishes, trimmed and sliced thin2 ounces (2 cups) watercress

Before You Begin

Be sure to use large eggs that have no cracks and are cold from the refrigerator. If you don't have a steamer basket, use a spoon or tongs to gently place the eggs in the water. It does not matter if the eggs are above the water or partially submerged.

Instructions

  1. Bring 1 inch water to rolling boil in large saucepan over high heat. Place eggs in steamer basket in single layer. Transfer basket to saucepan. Cover, reduce heat to medium-low, and cook eggs for 11 minutes.
  2. When eggs are almost finished cooking, fill medium bowl halfway with ice and water. Using slotted spoon, transfer eggs to bowl of ice water and let sit for 15 minutes to cool.
  3. Peel eggs and halve lengthwise. Transfer egg yolks to large bowl. Using potato masher, mash yolks with mayonnaise, yogurt, lemon juice, mustard, ½ teaspoon salt, and ⅛ teaspoon pepper. Whisk mixture until smooth.
  4. Chop egg whites into ¼-inch pieces. Fold whites and scallions into yolk mixture and refrigerate for 30 minutes. Season with salt and pepper to taste. Spread egg salad evenly over 6 bread slices. Arrange radishes evenly over egg salad, then top with watercress. Top with remaining 6 bread slices. Serve.

Why This Recipe Works

To achieve creaminess without relying solely on mayo, we took a cue from our method for deviled eggs and mashed the yolks. Knocking a few minutes off the cooking time produced yolks that mashed up perfectly creamy, with no hint of chalkiness. From there, we added just 2½ tablespoons of mayonnaise and an equal amount of yogurt, plus lemon juice, mustard, salt, and pepper. This yielded a velvety base into which we folded the chopped egg whites and fresh scallions. For crunch, we added a layer of vibrant radishes. And we traded the token lettuce leaf for a mound of vitamin-rich watercress for freshness.
