Yeah tuna with baked potato sounds weak but every meat has its companions, tuna sashimi or tuna in sushi in general is pretty great.

The supermarket beef I was imagining as op was talking burgers is that foul low grade ground beef that I used to eat when I was a broke apprentice. Rancid smell and tons of greasy, watery liquid to drain off... And then I found a butcher who sold their ground beef for a similar price because it was basically a byproduct of their steaks! That was it for supermarket ground, never again
