Soak skewers. If using wooden skewers, cover 6 of them with water and let soak until ready to use.
Marinate beef. Combine soy sauce, garlic, ginger, black pepper, and five-spice powder in a medium bowl. Add beef and toss to combine. Cover and chill for an hour.
Make skewers. Heat broiler to high and arrange rack in the lower third of the oven. Thread 4 pepper pieces and 3 beef pieces onto each skewer, starting and ending with the pepper, alternating between each. *See note if you want to be super scientific.
Broil skewers. Place on a baking sheet and broil about 8 minutes for medium-rare or 10 minutes for medium or until your desired doneness. Enjoy!
