Beef Pepper Fajita: How to make Beef Pepper Fajita

I will be posting the recipe for Beef Pepper Fajita soon. It tastes just like beef pepper steak and is very delicious indeed. Better than beef pepper steak because you don't have to cut it into smaller pieces while eating! Beef is already in bite-size form.
This is eaten with longitudinal buns (hamburger buns) or whatever way you like.
