Preheat your oven to 350°F (175°C).
Slice the homemade bagels in half horizontally and place them on a baking sheet.
Toast the bagels in the preheated oven for about 5-7 minutes or until they are slightly crispy.
While the bagels are toasting, prepare the toppings. Thinly slice the tomato, red onion, and set aside.
Spread a generous amount of cream cheese on each toasted bagel half.
Top the cream cheese with a few slices of Irish smoked salmon.
Add a few slices of tomato on each bagel half.
Sprinkle some thinly sliced red onion and capers on top.
Season with salt and pepper to your liking.
If desired, garnish with fresh dill for an extra pop of flavor.
