Code:

J + R = ( 9 + 18 - 1 ) = 26 = Z.

SALAD + ROMAN = ( 18 + 19 - 1 ), 15, ( 12 + 13 - 1 ), -1(!), ( 14 + 4 - 1 )
= ?OX?Q

So, SALAD + ROMAN probably doesn't factor in, at least not directly.

Aside from that, all I could see was "L is kinda like J" and "Both words are Consonant Vowel Consonant Vowel Consonant." I thought I saw a patter with R-S and L-M, but that was wishful thinking on my part.
