Heat oven to 375°F. Separate dough into 8 triangles. Place in ungreased 9-inch square pan or 10-inch pie plate; press in bottom and up sides to form crust.
In 10-inch skillet, cook beef over medium heat 8 to 10 minutes, stirring occasionally, until thoroughly cooked; drain. Stir in pizza sauce and bell pepper; simmer 5 minutes. Spoon beef mixture in crust-lined pan; sprinkle with cheese. Top with pepperoni.
Bake 14 to 17 minutes or until crust is deep golden brown and cheese is melted. Served topped with basil.
