Prepare the beet greens (and stems) - Separate the beet greens from the stems. Chop and wash the stems, then steam them for about 10 minutes. While the stems are steaming, chop and wash the greens, then add them to the steamer for the last two minutes. Drain, salt, and let cool.
Make the salad dressing and prep the apples - Whisk together the olive oil and balsamic. Peel the apples and slice them into matchsticks, then cut the matchsticks into cubes.
Toss the salad and garnish - Toss the salad dressing with the beet greens and stems. Add the apples and toss again. Crumble the goat cheese on top.
