Ingredients

• Nonstick vegetable oil spray
• 2 8-ounce red-skinned sweet potatoes (yams), halved lengthwise
• 1 teaspoon extra-virgin olive oil
• 1 teaspoon curry powder
• 1 cup plain nonfat yogurt
• 1 plum tomato, seeded, chopped
• 2 tablespoons chopped fresh cilantro
• 2 green onions, chopped

Instructions

1. Preheat oven to 400°F. Spray small baking sheet with nonstick spray. Drizzle cut sides of sweet potatoes with 1 teaspoon olive oil. Place potatoes, cut side down, on prepared sheet. Roast until tender and brown, about 30 minutes. Cool to room temperature.
2. Stir curry powder in small skillet over medium-low heat until fragrant, about 30 seconds. Remove from heat. Mix nonfat yogurt, tomato, fresh cilantro, and curry powder in small bowl. Season to taste with salt and pepper. (Roasted sweet potatoes and yogurt topping can be prepared 2 days ahead. Cover separately and refrigerate.) Serve sweet potatoes cold or at room temperature topped with chilled yogurt topping and chopped green onions.
