rasher

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

'food' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for rasher that I've seen before include "More foolhardy than a slice of bacon" , "Slice of meat - more reckless" , "Piece of bacon (6)" , "eat this?" , "Less considered" .)

I've seen this clue in The Hindu.
