Panel 1: The place: the Pattermanse's kitchen. The time: a few hours before dinner. The players: John and Elly. We start with Elly-the-perennially-martyred looking in the freezer section of the fridge and telling John that they could have coq au vin or Beef Stroganoff.
Panel 2: She whimsically declares in a ridiculously hammy French accent that ze chef will make ze delicacy of his choice.
Panel 3: He replies that he'll eat anything just so long as it's something he can recognize.

Summary: In the real world, it would have been obvious that Rod is a firm believer in the trinity that English Canadians really worship: meat and two veg. That means that on special occasions, he'll gladly eat the best food but on a day-to-day basis, he prefers the simpler things. This is not, of course, to say that he'll eat the same damned thing night after night; that's just how Lynn misinterpreted his refusal to play along with her fantasy that she was Julia Child.
