Cook and drain vermicelli as directed on package.

In large bowl, beat egg. Stir in Parmesan cheese. Add cooked vermicelli; toss to coat. Spoon mixture evenly into pie pan, pushing mixture up sides of pan to form crust.

In 12-inch skillet, cook ground beef, bell pepper and onion over medium-high heat, stirring frequently, until beef is thoroughly cooked; drain. Stir in pasta sauce. Spoon evenly into vermicelli-lined pie pan.

In small bowl, mix topping ingredients. Drop mixture by rounded teaspoons over filling.

Bake 25 to 30 minutes or until pie is thoroughly heated and crust is light golden brown. Let stand 10 minutes. Enjoy!
