Ok being serious then, the meme (& most people) refer to working class British dishes like fish & chips, beans on toast, bangers and mash which don’t have a lot of spice used in them. Many of them were probably invented, adapted & popularized by working class people during post world war 2 rationing.

I’m sure authentic British recipes do contain “rich people” food, but memes and pejoratives about their cuisine ignores or doesn’t know about such food.

Its like a meme mentioning American food as burgers & gravy, while pedants would argue Mexican food is also American. Ignoring why North Americans (mostly poor people) eat fast food and the socio-economic factors that forces them to eat low nutrition food.
