Making Grilled Steak Kabobs is simple when you follow these structured steps:

1. Prepare Marinade: In a bowl, mix the soy sauce, olive oil, Worcestershire sauce, honey, minced garlic, black pepper, salt, smoked paprika, and dried oregano until well combined.
2. Marinate the Steak: Place the cubed sirloin steak in a resealable plastic bag or a shallow dish. Pour the marinade over the beef, ensuring all pieces are coated. Seal or cover and refrigerate for at least 30 minutes or up to 4 hours for a deeper flavor.
3. Prepare the Vegetables: While the steak marinates, chop the bell peppers, onion, and zucchini into bite-sized pieces.
4. Preheat Grill: Preheat your grill to medium-high heat (about 400°F).
5. Assemble Kabobs: Thread the marinated steak and vegetables onto the skewers, alternating between meat and veggies for color and taste. Leave a little space between the pieces for even cooking.
6. Grill the Kabobs: Place the skewers on the grill. Cook for about 10-15 minutes, turning occasionally, until the steak reaches your desired doneness and the vegetables are tender.
7. Rest: Remove the kabobs from the grill and let them rest for a few minutes before serving. This allows the juices to redistribute throughout the meat.
