In a bowl, mix the Philadelphia cheese with chopped dill and lemon juice using a spoon. Add salt and pepper to taste.
In another bowl, crumble the albacore tuna with a fork and mix it with the mayonnaise and chopped flat-leaf parsley. Add salt and pepper to taste.
Peel the cucumber and cut it into thin slices.
For the sandwich bread sandwiches, spread the tuna mixture on the slices of bread, top with thin slices of cucumber, and add some spinach leaves. Cover with a second slice of sandwich bread. Gently press to compact each sandwich.
For the salmon tortillas, spread the tortillas on the work surface. Spread the seasoned Philadelphia cream cheese over the entire surface, lay flat cucumber slices over the entire surface, leaving 0.8 inches of space at the edges, and finish with a slice of smoked salmon per tortilla. Roll each tortilla tightly to enclose the filling.
Place the sandwiches in the refrigerator for about an hour, covered with plastic wrap to keep them fresh. Once chilled, slice the sandwich bread sandwiches into three pieces lengthwise and the salmon wraps into approximately 0.8-inch-wide sections.
