This recipe comes to us from chef Gianni Respinto of Darrel and Oliver's East City Grill in Fort Lauderdale, Florida. Gianni likes to serve this as salad plate, combined with his Black Bean and Pineapple Salsa and Macadamia and Banana Crusted Chicken.

Boniato, also known as tropical sweet potatoes are readily available in Florida.

While boniato and plantains are cooking:
Place milk and butter in a small saucepan. Split vanilla bean in half and scrape seeds into milk. Put the rest of the bean in the milk and bring to a simmer. Turn off heat. Remove the whole pieces of vanilla bean just before mixing milk mixture with boniato and plantains.
