Instructions
In a medium bowl, whisk together olive oil, soy sauce, Worcestershire sauce, minced garlic, dried oregano, salt, and pepper until combined.
Add the steak cubes, toss to coat evenly, cover, and refrigerate to marinate for at least 30 minutes and up to 4 hours.
If using wooden skewers, soak them in water for 30 minutes to prevent burning.
Preheat the grill to medium-high heat (about 400–450°F). Oil the grates lightly.
Thread marinated steak, bell peppers, red onion, and mushrooms onto skewers, alternating for even distribution.
Grill for 8–10 minutes, turning occasionally, until the steak reaches your desired doneness (about 135°F for medium-rare, 145°F for medium) and the vegetables are tender with light char.
Transfer to a platter and let rest for 3–5 minutes before serving. Enjoy hot.
