After all, I scamper back to get something to eat (8)
I believe the answer is:
'something to eat' is the definition.
(tortilla is a kind of food)
'after all i scamper back' is the wordplay.
'after' means one lot of letters go next to another.
'scamper' becomes 'trot' (I've seen this in another clue).
'back' says the letters should be written backwards.
'alli' put next to 'trot' is 'allitrot'.
'allitrot' in reverse letter order is 'TORTILLA'.
'to get' acts as a link.
(Other definitions for tortilla that I've seen before include "Mexican dish" , "Mexican maize pancake" , "Thin unleavened pancake" , "In which one may see salsa" , "Mexican 7 across" .)
