tucks in

I'm a little stuck... Click here to teach me more about this clue!

'eats heartily' is the definition.
The definition and answer can be both related to consumption as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?

'friar's at home' is the wordplay.
'friar's' becomes 'tuck's' (Friar Tuck).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'tucks'+'in'='TUCKS IN'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for tucks in that I've seen before include "has hearty meal" , "Greedily eats" .)
