Comparatively ill-considered option for your breakfast plate? (6)
I believe the answer is:
rasher
'comparatively ill-considered' is the definition.
('rash' can be a synonym of 'ill-considered')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rasher that I've seen before include "more hastily done" , "Less considered" , "A bit of bacon" , "eat this?" , "Thin slice of bacon" .)
