Prepare the Herb Cream Cheese: In a small bowl, combine the softened cream cheese with dill, capers, garlic, a pinch of salt, and black pepper to taste.
Toast the Bagels: Toast the halved bagels to your desired crispness in a toaster or a preheated oven at 350°F (180°C) for about 2 minutes or until golden brown.
Assemble the Bagels: Spread a generous layer of the herb cream cheese on each toasted bagel half. Place cucumber ribbons on the cream cheese, followed by slices of avocado.
