Ingredients

Scale

Dressing and Filling

2 tbsp extra-light mayonnaise
1 tbsp reduced-sugar ketchup
2 tbsp chopped dill (divided)
Juice of 4 lemon wedges (from 1 lemon cut into 8 wedges)
100g pack cooked and peeled North Atlantic prawns
½ cucumber, deseeded and diced
2 handfuls cherry tomatoes, halved

Assembly

20g bag rocket
2 slices wholemeal bread
4 lemon wedges, for serving

Instructions

Prepare the dressing: In a medium bowl, combine 2 tablespoons of extra-light mayonnaise, 1 tablespoon of reduced-sugar ketchup, half of the chopped dill, the juice squeezed from 4 lemon wedges, and a pinch of salt and pepper. Mix well until smooth to create a tangy, flavorful dressing.
Toss the filling: Add the cooked and peeled North Atlantic prawns, diced cucumber, and halved cherry tomatoes into the bowl with the dressing. Gently toss everything together until the prawns and vegetables are evenly coated with the dressing.
Assemble the sandwiches: Lay out two slices of wholemeal bread on separate plates. Evenly distribute the rocket leaves over the bread slices to provide a fresh, peppery base.
Top with prawn filling: Pile the prawn, cucumber, and tomato mixture on top of the rocket-covered bread, creating an attractive open-faced sandwich.
Garnish and serve: Scatter the remaining chopped dill over the top for added color and flavor. Serve with the remaining lemon wedges on the side, allowing diners to squeeze fresh lemon juice over their sandwich just before eating for a bright finish.

Notes

Use extra-light mayonnaise and reduced-sugar ketchup to keep the sandwich light and suitable for lower-calorie diets.
Ensure the cucumber is deseeded to avoid adding extra moisture and maintain a crunchy texture.
Serve immediately to keep the bread from becoming soggy.
