Ingredients
1 pound beets
1/2 teaspoon grainy mustard
2 tablespoons sherry vinegar
Pinch of sugar
6 tablespoons extra-virgin olive oil
Salt and freshly ground pepper, to taste
1 large bunch arugula
Preparation
Heat oven to 400 degrees. Wash beets and cut the stalks to 1/2 inch. Reserve beet greens. Put beets on a sheet of aluminum foil and form a pouch, sealing tightly. Place on a baking sheet and bake for 35 minutes.
Remove from oven and allow beets to steam in pouch 10 minutes longer. Take beets out of pouch; place in refrigerator. When cool, slip beets out of their skins and slice. Set aside.
To make vinaigrette, whisk together mustard, vinegar, and sugar in a small bowl. Slowly whisk in the oil, and season with salt and pepper.
Toss beets with the vinaigrette and serve on a bed of arugula.
