In a bowl, whisk together olive oil, soy sauce, Worcestershire sauce, minced garlic, oregano, thyme, rosemary, pepper, and salt.
Place the steak cubes in a large resealable bag. Pour the marinade over the steak, seal the bag, and ensure all pieces are well coated. Marinate in the refrigerator for at least 1 hour.
Preheat the grill to medium-high heat.
Thread the marinated steak, bell pepper, red onion, cherry tomatoes, mushrooms, and zucchini slices alternately onto skewers.
Place the skewers on the grill. Cook for 10-15 minutes, turning occasionally, until the steak reaches the desired doneness.
Remove the kabobs from the grill and let them rest for a few minutes before serving.
