Preheat broiler at full heat. Mix egg in small mixing bowl. Brush egg mixture on edges of wonton wrapper. Cube brie and place in center of wrapper. Add about 5 pine nuts (if you like them crunchy you can broil them with the spray oil before adding).
Fold opposite corners of wrapper together and press firmly to seal. Spray wontons lightly with oil.
Place in broiler and watch closely until golden brown. Serve with your favorite sauce (barbecue, mango salsa, soy sauce...)
