A grill-friendly take on stuffed hasselback sweet potatoes

To be honest, it's hard not to get inspired by hasselback potatoes, those deliciously crisp and creamy potatoes that are thinly sliced so they fan out accordion-style during roasting. The edges take on lovely french fry qualities, while the insides stay moist and tender. Add a serious splash of butter or oil and they can be pretty heavenly.
