Mix black pepper and smoked paprika together in a bowl; season 1 side of each chicken breast with black pepper mixture.

Preheat the grill to 300 degrees F (150 degrees C). Soak 8 toothpicks in a bowl of water.
Remove plastic wrap from chicken breasts and place chipotle-side down on a work surface. Spoon the vegetable mixture onto each chicken breast; roll chicken breast around filling. Secure each breast with 2 toothpicks. Season outside of rolls with more ground chipotle.
Grill chicken breasts until no longer pink in the center and the juices run clear, about 30 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
