Tote two peas around as a vegetable (5,6)
I believe the answer is:
sweet potato
'a vegetable' is the definition.
(I know that sweet potato is a type of vegetable)
'tote two peas around' is the wordplay.
'around' is an anagram indicator.
'tote'+'two'+'peas'='totetwopeas'
'totetwopeas' is an anagram of 'SWEET-POTATO'.
'as' is the link.
(Other definitions for sweet potato that I've seen before include "Yam-like vegetable" , "Slightly sugary root vegetable" , "Paste too wet (anag.)" , "Edible root of the Americas" , "Vegetable akin to yam" .)
