Pleasant stroll around Iowa (7)
I believe the answer is:
amiable
'pleasant' is the definition.
(thesaurus)
'stroll around iowa' is the wordplay.
'stroll' becomes 'amble' ('amble' can be a synonym of 'stroll').
'around' means one lot of letters goes inside another.
'iowa' becomes 'ia' (standard US state two-letter abbreviation).
'amble' going around 'ia' is 'AMIABLE'.
(Other definitions for amiable that I've seen before include "'Friendly, pleasant and good-tempered (7)'" , "Friendly, kindly" , "'Cordial, friendly (7)'" , "Charming" , "Lovable, friendly" .)
