Mind you it’s better than someone who is very close to me (you could say we were married) who likes to dollop ketchup alongside her steamed salmon. I’m not sure a word exists that describes the evilness that this is pertaining to. I mean, ketchup and salmon… bleuch.. (I’m hoping that the ketchup in question isn’t green).
However I should temper this with my own guilty admissions. Tuna, Smash (Instant potato) and beans make a quick healthy dinner (sort of…). Banana, ham, and cheese sandwiches. Actually ignore that, they’re STILL not as bad as ketchup with steak.
