To make the salad, you first need to prep the watermelon radishes and oranges. 

You can choose to cut the radishes into moon half-slices, circular slices, or into carpaccio-style slivers using a mandoline. You do not need to peel the radishes. 

Cut a small piece of the orange rind at the bottom of each orange and squeeze the juice on the radishes. Use a sharp knife to remove the peel completely. Now, cut the orange membranes to release the fruit flesh and chop them into bite-size pieces. 

In a salad plate, assemble the watermelon radishes, then the orange segments, and finally sprinkle the goat cheese and walnuts. 

Now, drizzle the balsamic vinegar and olive oil. Season with salt and pepper and let it rest for 5 minutes. Garnish with minced chives. Your salad is ready to be enjoyed!
