Place the chicken breast cutlets into a large heavy-duty Ziploc bag.
In a small bowl, whisk together lemon juice, canola oil, honey, Dijon mustard, smoked paprika, thyme, salt, and black pepper.
Pour the marinade over the chicken in the bag, seal, remove air, and refrigerate for 1 to 2 hours.
Preheat the outdoor grill to 400°F.
Grill the marinated chicken breasts with the lid closed for 6 to 8 minutes on one side.
Flip the chicken and grill for another 6 to 8 minutes or until the internal temperature reaches 165°F.
Remove the chicken from the grill and turn off the grill following manufacturer instructions.
Allow the chicken to rest for 5 minutes before slicing and serving.
