granca,
Check out this link and the vegetable called
pana. If that's what you are referring to then it's bread fruit.

Buen pan is also bread fruit and it has several different names in Spanish. It varies by country. It was first brought to the Caribbean during colonization (aka slavery) and became a key staple vegetable in many islands principally Jamaica but can be found and eaten by the locals in the Bahamas, DR, Puerto Rico, St. Vincent,Trinidad and other islands. A lot of West Indians eat bread fruit in general.
Buen pan is the DR name but I don't call it that. I call it pana (Puerto Rico). Other common names are:
panapén and
fruta del pan.
