Struggling home late, almost, this gives one an inner warmth (3,4)

'gives one an inner warmth' is the definition.
I can't judge whether this defines the answer.

'struggling home late almost' is the wordplay.
'struggling' indicates an anagram (the letters struggle or wriggle into a new form).
'almost' means to remove the last letter (most of the word but not all of it).
'home'+'late'='homelate'
'homelate' with its last letter removed is 'homelat'.
'homelat' is an anagram of 'HOT MEAL'.

'this' is the link.

Can you help me to learn more?
