01 - In a bowl, mix cream cheese, dill, salt, and pepper until smooth and fully incorporated. Set aside at room temperature for easy spreading.
02 - Mash hard-boiled eggs in a bowl with a fork until crumbly but not completely smooth. Stir in mayonnaise, Dijon mustard, chives, salt, and pepper until well combined.
03 - Combine softened butter with parsley and lemon juice in a small bowl. Mix thoroughly until herbs are evenly distributed. Season generously with black pepper.
04 - Lay out all bread slices on a clean work surface. Press a large heart-shaped cookie cutter firmly into each slice to cut out as many heart shapes as possible. Reserve scraps for another use or discard.
05 - Spread cream cheese mixture evenly on half of the white bread hearts. Arrange thin cucumber slices over the cheese, then top with remaining white bread hearts to create sandwiches.
06 - Spread egg salad generously on half of the whole wheat bread hearts. Place remaining whole wheat hearts on top to form sandwiches, pressing gently to adhere.
07 - Spread herbed butter on remaining bread hearts (white or rye). Layer smoked salmon pieces over the butter, then sandwich with remaining bread hearts.
08 - Place finished sandwiches on a large serving board or platter, alternating varieties and arranging in an attractive pattern. Leave space between sandwiches for garnishes.
09 - Scatter radish slices, microgreens, and edible flowers around and between sandwiches. Place lemon wedges along the edges for a decorative touch and fresh accent.
10 - Serve immediately for best texture and flavor. Alternatively, cover board lightly with plastic wrap and refrigerate for up to 2 hours before serving. Do not leave at room temperature longer than 2 hours.
