Extremely glad to eat our fruit (5)
I believe the answer is:
gourd
'fruit' is the definition.
(I've seen this before)
'extremely glad to eat our' is the wordplay.
'extremely' means to remove the middle letters.
'to eat' means one lot of letters goes inside another.
'glad' with its middle removed is 'gd'.
'gd' enclosing 'our' is 'GOURD'.
(Other definitions for gourd that I've seen before include "Pumpkin, e.g" , "Squash, for example" , "Hard-skinned fruit" , "Bottle, dishcloth, plant" , "Hard-rinded fruit often used as container" .)
