Anyone fulfilling his obligation of hearing kidush must eat a meal (or a nominal meal) at the same time and in the same place. There are details ‐ see Shulchan Aruch, Orach Chayim 273 — but that's the general rule. My question is whether the meal must follow the kidush or whether, on the contrary, even a meal concluded with kidush is sufficient for the requirement of eating a meal with kidush.
A hypothetical to which my question applies is that of someone who did not hear kidush, ate a meal (or a nominal meal), then realized his error (one may not eat before kidush) and made or heard kidush immediately on concluding his meal (before the meal's after-b'racha, or perhaps after). Would he then need to eat after kidush also?
