What the fuck are mesclun greens

I do not believe that people are meant to find bitter things tasty. If it tastes like fucking poison, we are not meant to eat it, because it is likely bad for us, if not downright lethal. This is probaby a selection trait. If it's bitter and nasty, it's probably bad, therefore anyone stupid enough to eat poisonous plants should be weeded out of the gene pool, and the taste for bitter shit should lessen with each subsequent generation. So I do not understand why it's suddenly trendy to want to eat these salads that are made up of greens that look like they've just been yanked out of someone's window boxes, and taste like carpet cleaner, with one fucking miserable cherry tomato for color. I want a real salad, not your fucking geranium leaves with dandelion stalks and brillo shavings. Fuck off with it, Jean-Claude, I want salad, not poison.
