Preheat oven to 400˚F. Grease a rimmed baking sheet with cooking spray.
Add cherry tomatoes in an even layer to the prepared baking sheet. Roast tomatoes until they begin to burst, about 10 minutes, turning halfway through cooking.
While the tomatoes are roasting, make the chipotle cream cheese. In a small bowl, stir together cream cheese, adobo sauce, and 2 chopped chipotle peppers until combined. Set aside until ready to use.
In a small bowl, stir together mashed avocado, lime juice, black pepper, and salt.
Toast the bagel halves until golden brown.
To assemble, spread the bottom halves of the toasted bagels with mashed avocado mixture, dividing evenly between the two.
Divide the cream cheese evenly between the two top halves of the bagels, spreading evenly.
Add turkey to the bottom halves of the bagels and top with mixed greens and burst cherry tomatoes. If desired, top with additional chopped chipotle peppers.
Finish with the top halves of the bagels. Serve immediately.
