- 1 cup soy sauce
- 1/2 cup black soy sauce
- 1/4 cup ponzu sauce
- 1/4 cup brown sugar
- 1 Tbsp. freshly ground black pepper
- 1 pound boneless beef striploin , cut into 1-inch cubes
- 4 red bell peppers , cut into 1-inch pieces
- 8 8-inch bamboo skewers , soaked in water for 30 minutes
Evenly distribute the cubed beef between the skewers. Place a piece of beef on first, then add a piece of red bell pepper. Continue until all of the skewers are prepared. Pour the marinade over the beef skewers and allow them to marinate overnight, or for a minimum of 6 to 8 hours.
Preheat your grill or flat top. Place the skewers on the grill and cook for 4 minutes on each side, turning as needed.
