In the Instagram era, it’s more important for food to LOOK good than taste good. Which is how we end up with stuff like this . . . the new, trendy vegetable on sale is PINK LETTUCE. It’s not artificially dyed, and it’s called “pink radicchio”. It’s got a slightly bitter taste, and it’s starting to show up at stores like Whole Foods. It WILL make your salad look more photogenic, but it’s gonna cost you. It sells for about five times more than regular green lettuce.
