Tangy and aromatic, celeriac (or celery root) has long been a staple in French cooking. Here, it's combined with parsnips and russet potatoes for a side dish worthy of your favorite bistro--or trattoria, because we've relocated the dish south, from Paris to Tuscany, using olive oil and Parmesan cheese. The potato is kept separate from the celeriac and parsnip because it gets gluey when pureed in a food processor.

-
1 medium celeriac, (about 1 pound), peeled and cut into 1-inch cubes
-
3 medium parsnips, (about 3/4 pound), peeled and cut into 1-inch slices, thick ends quartered
-
1 large russet potato, (about 3/4 pound), peeled and quartered
-
1/4 cup vegetable broth, or reduced-sodium chicken broth
-
2 tablespoons extra-virgin olive oil
-
3 tablespoons chopped fresh chives, divided
-
2 tablespoons low-fat or nonfat plain yogurt
-
1 1/2 teaspoons Dijon mustard
-
1/2 teaspoon salt
-
Freshly ground pepper, to taste
-
1/2 cup freshly grated Parmesan cheese
With all that delicious fruit an apple pie should be healthy, but the truth is a slice can have as much as 750 calories and 30 grams of fat. For the most part, the culprit is the crust. We use whole-wheat pastry flour to add fiber and lower the saturated fat by replacing some of the butter with canola oil. The brown sugar-sweetened filling in this pie is made with two kinds of apples for the perfect balance. A slice has half the calories of a typical version and only 10 grams of fat--sweet!
