1 1/4 cups canned pumpkin
2 tablespoons dry breadcrumbs
2 tablespoons fresh grated Parmesan cheese
1/2 teaspoon salt
1/2 teaspoon minced fresh sage
1/4 teaspoon freshly ground black pepper
1/8 teaspoon ground nutmeg
30 round wonton wrappers
1 tablespoon cornstarch
1 cup fat-free milk
1 tablespoon all-purpose flour
1 1/2 tablespoons butter
1/2 cup (2 ounces) crumbled Gorgonzola cheese
3 tablespoons chopped hazelnuts, toasted
Spoon pumpkin onto several layers of heavy-duty paper towels, and spread to 1/2-inch thickness. Cover with additional paper towels; let stand 5 minutes. Scrape into a medium bowl using a rubber spatula. Stir in breadcrumbs, Parmesan, salt, minced sage, pepper, and nutmeg.
Working with 1 wonton wrapper at a time (cover remaining wrappers with a damp towel to keep from drying), spoon 2 teaspoons pumpkin mixture into the center of wrapper. Brush edges of wrapper with water and fold in half, pressing edges firmly with fingers to form a half-moon. Place on a large baking sheet sprinkled with cornstarch. Repeat procedure with remaining wonton wrappers and pumpkin mixture.
Fill a large Dutch oven with water; bring to a simmer. Add half of ravioli to pan (cover remaining ravioli with a damp towel to keep from drying). Cook 4 minutes or until done (do not boil), stirring gently. Remove ravioli with a slotted spoon; lightly coat with cooking spray, and keep warm. Repeat procedure with remaining ravioli.
