Ingredients

4 medium russet potatoes, about 8 ounces each 

1 tablespoon olive oil 

8 ounces cremini mushrooms, stemmed and cut into 1/4-inch-thick slices 

1/4 teaspoon coarse salt 

Freshly ground pepper 

2/3 cup grated white cheddar cheese 

1/4 cup plain low-fat (2 percent) yogurt 

Finely chopped fresh chives, for garnish 

Preparation

Preheat oven to 450 degrees. Bake potatoes on a rimmed baking sheet until skins are crisp and flesh is tender, 45 to 50 minutes.

Heat oil in a medium skillet over medium-high heat. Add mushrooms; cook, stirring, until browned, about 2 minutes. Stir in salt; season with pepper.

Slit the potatoes lengthwise, stopping 1/2 inch from ends. Gently squeeze ends to loosen flesh. Open each potato slightly. Divide sauteed mushrooms and the cheese among potatoes; top each with 1 tablespoon yogurt. Garnish with chives.
