I guess I would say "fake food" is something that:
1. Bears little resemblance to anything found in nature
2. Is impossible to replicate at home (I can’t make Kraft Mac and cheese or Spam from "scratch" in my home kitchen).
Perfect! Perfect description…
My wife, despite constantly crediting me with broadening her food horizons (she grew up here in Cincinnati, but had never eaten at Frisch’s Big Boy or had Cincinnati chili when we met….), has a weakness for this sort of stuff. On those rare evenings when I go out by myself (to the opera, or to a meeting at our parish), leaving her and our son home alone, she will ask that I purchase the makings for her favorite "fake food" meal: Hamburger Helper (Cheeseburger Macaroni variety) and "tube biscuits" (Pillsbury, naturally).
*sigh*….the struggle continues….
