Turnips are not cauliflower. Turnips are edible ate many of them raw right out of the ground, of course food was a little more rare then, where I lived. I can eat cauliflower or broccoli if they are smothered in cheese, otherwise I don't care how healthy they claim it is, feed it to the chickens.
When I was a kid meals were very predictable, beans and potatoes with cornbread or hot rolls and occasionally corn that was so tough cows couldn't eat it.
Well, no they aren't. Didn't claim they were.
