Drink in pot, easy! (3)
I believe the answer is:
tea
'drink' is the definition.
(tea is a drink)
'in pot easy' is the wordplay.
'in' indicates a hidden word.
'TEA' is hidden in the letters of 'pot easy'.
(Other definitions for tea that I've seen before include "Provide a meal" , "bush" , "Shrub; drink" , "Cha" , "Beverage; meal" .)
