I believe the answer is:

polenta

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

'food from italy' is the definition.
'polenta' can be an answer for 'food' (I've seen this before). I'm not sure about the 'from italy' bit.

'dad eating ordinary fast' is the wordplay.
'dad' becomes 'pa' ('pa' can be a synonym of 'dad').
'eating' means one lot of letters goes inside another.
'ordinary' becomes 'o' (abbreviation e.g. O-Levels).
'fast' becomes 'lent' (I've seen this before).
'o'+'lent'='olent'
'pa' placed around 'olent' is 'POLENTA'.

(Other definitions for polenta that I've seen before include "Lepanto (anag.)" , "Maize flour dough" , "Italian maize dough" , "Italian dish of maize flour" , "Italian maize paste" .)
