A croissant isn't worth eating in or out of a blender.
Recently I've had the opportunity to test my blender theory.
My wife and I went on a diet. We had 3 days of fasting and then went to smoothies. Most of the smoothies were bland so I began "cooking" my smoothies. By that I mean seasoning them and adding trace elements of this or that to give things a good flavor.
I did heat one or two. I made an excellent spinach lasagne smoothie that, while not as good as the real thing because there wasn't any cheese in it except some cottage cheese, was very recognizable as a smoothie.
I thought the smoothies would be horrible but now we are continuing a smoothie a day and have found some really cool combinations. I never thought I'd ever say something other than a fruit smoothie would even be edible.
