- ½ cup olive oil
- ½ cup soy sauce
- 3 cloves garlic, minced
- 1 teaspoon black pepper
- 2 pounds sirloin steak, cut in 1-inch cubes

- 1 green bell pepper, seeded and cut in 1-inch pieces
- 1 red onion, cut in 1-inch pieces
- 8 (12-inch) metal skewers
- In a medium bowl, whisk together olive oil, soy sauce, garlic and pepper. Add the cubed sirloin steak to marinade and toss to coat. Cover with plastic wrap and let marinate for 30 minutes or up to 1 hour.
- Once the meat has marinated, thread it onto the skewers alternating with pieces of bell pepper and red onion.
