Crack open the egg in a small bowl and beat well.
Cut the bananas to 3 cm length and divide into quarters.
Cut the chocolate to equal lengths as the banana.
Spread out the wonton wrapper and place the banana and chocolate slightly above the center. Roll the wrapper in the same method as the spring rolls (or burritos). Once the roll is finished, brush on the egg from Step 1 to keep the wrapper together.
Place the rolls on a baking sheet or aluminum foil and bake in the toaster oven for 10 minutes. Enjoy!
