The fresh produce section in our supermarkets are arranged so that you CAN take part of a head of broccoli or spinach or whatever. Hands of bananas can be broken up into a smaller bunch; potatoes, tomatoes, apples, and other things can be purchased singly as it seems that everything is sold by the pound.

We buy frozen veggies and fruits that are "flash frozen" with minimum processing. After the bag is opened as much air as possible is squeezed out and it is put into a Ziploc bag and air squeezed from that before it is all returned to the freezer.

"Hi, welcome to Burger King, where you can have it your way!"
"I'd like a triple pounder, but please hold the cheese, the meat, the bun, the ketchup, the mustard, the special sauce, the bacon, and the lettuce."
"Sir, that leaves only four slices of pickle!"
"Oh, hold them too. I don't like pickles."
"Ah, sir? Sir?"
