Start by boiling the eggs. Place them in a pot of water, bring to a boil, and let them cook for about 10 minutes. Afterward, cool them under cold water, peel, and chop them coarsely.
In a mixing bowl, combine the cooked prawns with the mayonnaise, lemon juice, and a pinch of salt and pepper. Gently fold in the chopped boiled eggs and mix until everything is well coated.
Lay the lettuce leaves on the slices of rye bread. Generously spoon the prawn mixture over the lettuce, making sure to cover the bread evenly.
Top the prawn mixture with cucumber slices and garnish with fresh dill sprigs. Add a slice of lemon on the side for an extra pop of color and flavor.
Slice the sandwiches in half for easy handling, and serve them on a platter. Your guests will love the handcrafted details and deliciously fresh flavors of Rksmrgs: Swedish Prawn Sandwich.
