Provide waffle right before I carve up pté sandwiches (11)

I believe the answer is:

prevaricate

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

'provide waffle right' is the definition.
I can't judge whether this defines the answer.

'i carve up pte sandwiches' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'pte' becomes 'prate' (I can't explain this - if you can you should give a lot more credence to this answer).
'sandwiches' means one lot of letters goes inside another (inserted letters are sandwiched in).
'i'+'carve'='icarve'
'icarve' anagrammed gives 'evaric'.
'evaric' put inside 'prate' is 'PREVARICATE'.

'before' is the link.

Can you help me to learn more?

(Other definitions for prevaricate that I've seen before include "Dither" , "Behave evasively" , "Beat about the bush" , "Deliberately withhold information" , "Dodge" .)
