Sweet Potato Salad

Ingredients
1-1/2 cups plain nonfat yogurt
1 Tbsp black pepper
1 Tbsp lime juice
2 stalks of celery, chopped
1 sweet green pepper
3 lb sweet potatoes
2 Tbsp shallots, minced
Canned chiles, to taste


Directions
Preheat oven to 400 degrees (200 degrees C). Wash, dry and pierce sweet potatoes several times with a fork. Place in the oven and bake for one hour until potatoes are soft. In a medium bowl prepare dressing by mixing together yogurt, minced shallots, lime juice and black pepper. Chill. Once potatoes are baked, cool and cut into small 1/2-inch (1 cm) cubes. Place potatoes into a large bowl and sprinkle with pepper. Cut seeded green bell pepper, celery and chiles and add to bowl, tossing ingredients until well blended. Just before serving, mix dressing into potato salad and serve.
