When and where I grew up, vegetables meant:
Potatoes (with practically every meal, and I hate boiled potatoes).
Carrots
Celery
Lettuce - usually Iceberg type
Tomatoes
Turnips
Canned mixed veggies, canned beets.
That was pretty much it, I think. Onion was used to "give taste" to things, along with salt and pepper.
20 years of that regimen left me taking for granted that practically anything that wasn't on that list was "exotic" and presumably expensive. Of course, before the mid 90's, those things were effectively "exotic" and/or unheard of.
I broaden my taste eventually, but I still assume that those products are expensive. Brocoli is one of my favorites. Spinach, too. I tried sweet potatoes 2 or 3 years ago and loved them. Parsnips I never tried.
And, Whole Foods, I mean... I love that place and we go every week, but they're so damn expensive. And they're also good at soaking their veggies so damn wet that they often rot w/in a day or two of bringing them home. I do understand a light mist every now and then, but nothing on the level of what WF does. Am I supposed to sit there with the hair dryer and dry my veggies when I unpack the groceries? I don't get it.
I also have yet to forgive them for that roast beef we bought from them when my mother-in-law was visiting in January. Coast us a fortune, and I was so excited to eat roast beef for the first time in years. Well, unless you were equipped with a dog's mouth, there's no way you could actually chew into it. I couldn't finish one bit - neither anyone at the table could.
They'd also sold us very poor steaks the year before, but I had assumed that my cooking was to blame. But looking back, it was just frickin' rubber.
