Meals served with hesitation — there's a problem (6)
I believe the answer is:
teaser
'a problem' is the definition.
(I've seen this before)
'meals served with hesitation' is the wordplay.
'meals' becomes 'teas' (tea is a kind of meal).
'served with' is a charade indicator (letters next to each other).
'hesitation' becomes 'er' (sound used when hesitating).
'teas'+'er'='TEASER'
'there's' is the link.
(Other definitions for teaser that I've seen before include "inducement" , "one using a backcomb" , "Difficult problem concerning Easter" , "Tricky question; intriguing preliminary advert" , "One who annoys people or cards wool" .)
