Soak skewers. If using wooden skewers, cover 6 of them with water and let soak at least 30 minutes or until ready to use.
Marinate beef. Combine 3 tablespoons soy sauce, 2 cloves minced garlic, 1 teaspoon minced ginger, 1/4 teaspoon black pepper, and 1/4 teaspoon five-spice powder in a medium bowl. Add 1 pound beef cubes 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!
