This is a deletion - look for an indicator word that suggests removing or taking away letters from another word.
'Doffing' indicates removal or taking off. Start with 'NOODLES' (what you 'see you' eating) and remove the first letter (the 'cap' or head of the word).
Answer: OODLES | 'Doffing cap' means removing the first letter. Take NOODLES (see you = SEA U sounds like 'see you', but more directly noodles are what you might 'see you' having) and remove the first letter N to get OODLES (a lot).
