In a medium bowl, combine the whipped cream cheese, chopped green onions, fresh dill, grated garlic, and black pepper.
Stir until smooth and well blended.
Cover and refrigerate until ready to assemble the sandwich.
Slice the bagel in half and toast until lightly golden.
Spread about 2 generous tablespoons of the garlic dill cream cheese mixture onto each toasted half.
On one half of the bagel, layer the smoked salmon evenly.
Add the tomato slices, cucumber slices, microgreens, pickled red onions, and capers.
Place the remaining bagel half on top.
For the signature presentation, carefully flip the completed Smoked Salmon Bagel Sandwich before slicing.
Slice in half, serve immediately, and enjoy.
