Sailor needing energy opts to eat processed, starchy food (6,8)

I believe the answer is:

jacket potatoes

'starchy food' is the definition.
(potatoes are starchy)

'sailor needing energy opts to eat processed' is the wordplay.
'sailor' becomes 'jack' (jack can informally mean a sailor).
'needing' is a charade indicator (letters next to each other).
'energy' becomes 'e' (physics symbol as in E=mca).
'processed' indicates an anagram.
'opts'+'to'+'eat'='optstoeat'
'optstoeat' anagrammed gives 'tpotatoes'.
'jack'+'e'+'tpotatoes'='JACKET POTATOES'
