1/4 cups chopped sweet onion such as Vidalia, Walla Walla, or Maui
1/4 cup mayonnaise
1 tablespoon honey Dijon mustard
eight 1/2-inch-thick slices multigrain bread (each about 4 by 2 1/2 inches)
Directions
In a small saucepan of boiling salted water cook beans until just tender, about 3 minutes. Drain beans and plunge into a bowl of ice and cold water to stop cooking. Remove beans from water and pat dry with paper towels.
Chop eggs and in a bowl stir together with celery, onion, mayonnaise, mustard, and salt and pepper to taste. Spread egg salad on 4 bread slices and top each sandwich with 4 beans and remaining bread slices.
