On one side of 4 slices of bread spread with 1 tablespoon cream cheese. Next, on top of cream cheese, spread each with 2 teaspoons strawberry preserves. Place ¼ cup strawberry slices on each. Top each with the remaining slice of bread to make a sandwich.
In a shallow bowl or pie plate, beat egg whites and vanilla.
Dip 2 sandwiches into the egg mixture, making sure to coat both sides.
Coat a large nonstick pan with cooking spray. Melt 2 teaspoons of reduced-fat butter and swirl around bottom of pan. Add 2 sandwiches, cook about 3 minutes on medium-high heat until golden. Turn over and cook the undersides for about 2 minutes, until golden brown. Place cooked sandwiches on a baking sheet and keep warm in oven while cooking the other 2 sandwiches.
Repeat steps 3 and 4 with 2 remaining sandwiches.
Transfer each sandwich to a plate. Cut each in half and sprinkle with 2 teaspoons powdered sugar and garnish with strawberry slices.
Serve immediately with a fork and knife. Enjoy!
