Sweet Potato Casserole With Praline Topping

• 1 cup all-purpose flour
• 2/3 cup packed brown sugar
• 1/4 cup chopped pecans, toasted
• 1/4 cup stick margarine, melted
• 1/2 teaspoon ground cinnamon
• 4 medium sweet potatoes, peeled and halved (about 21/2 pounds)
• 1/2 cup granulated sugar
• 1 1/2 teaspoons vanilla extract
• 1 large egg white
• 1 (5-ounce) can fat-free evaporated milk
• Cooking spray

Instructions:
Preheat oven to 350`. Combine first 5 ingredients in a small bowl, stirring to form a streusel. Set aside. Place potatoes in a Dutch oven; add water to cover. Bring to a boil; cover, reduce heat, and simmer 30 minutes or until very tender. Drain well; mash in a large bowl. Stir in 1 cup streusel, granulated sugar, vanilla, egg white, and milk. Spoon into a 2-quart casserole coated with cooking spray; top with remaining streusel. Bake at 350` for 45 minutes. Yield: 8 servings (serving size: 3/4 cup).

NOTE:
The streusel is both stirred into the casserole and sprinkled on top.
