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

'food on toast?' is the definition.
'spaghetti' can be an answer for 'food' (spaghetti is a kind of food). I am not certain of the 'on toast?' bit.

'get this and pa will be excited' is the wordplay.
'and' means one lot of letters go next to another.
'will be excited' is an anagram indicator.
'get'+'this'='getthis'
'getthis' after 'pa' is 'pagetthis'.
'pagetthis' with letters rearranged gives 'SPAGHETTI'.
