I just cut a bunch of oregano the other day and took the leaves off the stem and cut it up. I then lay them flat on a paper towel that is on a baking sheet and cover with another paper towel. Let it lay out for a week or so and then cut it up as small as you wish. This then works great in sauces.
As I was cutting the herbs my wife cleaned and cut up a few radishes for a salad. Had to take a picture of those also because they were so bright!
