Make the bagel chips: Set a wire rack over a baking sheet.
2. Step
Slice the bagels into ¼-inch-thick rounds. Arrange the slices in a single layer on the wire rack and brush both sides with the olive oil.
3. Step
Broil the bagels for about 6 minutes per side, until golden brown and crispy.
4. Step
Make the lox dip: In a medium bowl, combine the lox, cream cheese, red onion, dried garlic, sesame seeds, poppy seeds, and fennel seeds and fold with a rubber spatula until well incorporated. Transfer to a serving bowl and top with the capers and scallions.
5. Step
Serve the lox dip with the bagel chips and sliced tomatoes.
