Instructions

1. Step 1: Place 3 large eggs in a saucepan and cover with cold water. Bring to a boil over medium-high heat, then reduce to a simmer and cook for 10 minutes. Transfer eggs to ice water to cool, then peel and chop finely.
2. Step 2: In a medium bowl, combine 3 tbsp mayonnaise, 1 tsp Dijon mustard, 1 tsp lemon juice, 1/4 cup finely diced celery, 2 tbsp thinly sliced green onion, 1/2 tsp salt, and 1/4 tsp black pepper. Fold in the chopped eggs gently to make the egg salad.
3. Step 3: Mix 1/2 cup lump crab meat and 1/2 cup flaked cooked whitefish in a separate bowl, seasoning lightly with salt and pepper.
4. Step 4: Butter one side of 8 slices of rustic sandwich bread with 2 tbsp softened butter. Toast the bread slices in a skillet over medium heat until golden brown on both sides.
5. Step 5: To assemble sandwiches, layer a buttered slice with lettuce leaf, 1/4 of the crab and whitefish mixture, 1/4 of the egg salad, and top with another buttered bread slice. Repeat for remaining sandwiches.
6. Step 6: Cut sandwiches diagonally and serve warm or at room temperature.
