It's only been a few days. Personally I'd wait a week or two and see if you actually start to crave them.... you might! Unlike those highly-processed cooked foods you mentioned, your body actually loves and WANTS its greens!
Hahahahaa -- nothing like getting totally contradictory replies to your post, huh?
However you choose to handle this, jumping back on the horse or waiting it out, remember this aversion to these foods is all IN YOUR MIND, so ultimately you have the power to alter your perception of them and change the outcome!
You can also try using your greens in a smoothie, so there's no familiar "greens" taste associated with them.....
Good luck!
