Some eating cultures call for salad to be served alongside mains, or as part of a course of several small plates (mezze).
I, for one, cannot imagine eating kabobs or roast meats without a side of something fresh, sour, herbal, vegetal - i.e. salad. To me, there is no greater pleasure than spooning chopped cucumber, tomato and parseley on top of rice as a side to kofta or grilled chicken.
Similarly, even the most perfunctory street kababist in Egypt will serve a plate or plastic bag of chopped salad to be eaten alongside grilled meats and bread. Not before, not after, during.
While I didn't encounter many (or any) composed "salads" in India, all of the kabobs I ate came with at least a side of marinated onions, or sliced cucumbers and of course, chutney. In Northern Indian Kabob Cuisine (tm), a side of chutney/raita is de rigeur, and serves the same sour, fresh, herby purpose as does salad in the Arab Kabob context.
For the western style meals I grow up with in Chicago, we often served salad as a side to the main dish. If I couldn't combine my salad with the main in a meaningful way, I always preferred to eat it after I finished the spaghetti or whatever it was we were having.
My first experience eating salad post-meal was at a French/Romanian friend's home in Chicago. I thought it was pretty classy for some reason.
