I don't know if you have the greens too, or even if you're interested in a side dish sort of thing, but I'm posting this one too anyway.
1 tbsp oil 1 large shallot, minced 1 cup thinly sliced stemmed beet greens 1 recipe Basic Roasted Beets (see my other post) 1 tsp chopped fresh rosemary (or 1/4 tsp dried) Salt
In a large skillet, heat the oil. Add the shallot and cook until tender, 2-3 minutes. Add the beet greens; cook, stirring often, until wilted, about 3 minutes. Add the beets, cut into 1/2-inch wedges, and rosemary. Season with salt. Cook, stirring, until beets are just heated through, 2-4 minutes.
Serves 4 - per serving, 88 calories, 3.6g fat. Since the oil is just for sauteeing the shallot, you can even cut that in half and reduce the fat a bit more.
