I never liked to cook vegetables that involve time-consuming peeling, until I discovered (& trained) a meticulous helper.
Preparing sweet potato leaves:
1. Cut off the leaves.
2. Identify the thicker side of the stem.
3. Make 3 or 4 small peels at the top.
4. Pull these peels down and off.
5. Break into smaller pieces and peel off when more skin appears.
6. Discard the debris.
