Creating delicious Grilled Steak Kabobs is straightforward. Follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together olive oil, soy sauce, Worcestershire sauce, balsamic vinegar, minced garlic, smoked paprika, black pepper, and salt.
2. Marinate the Steak: Place the cubed steak in a resealable plastic bag or bowl, pour the marinade over it, and ensure all pieces are well-coated. Seal the bag or cover the bowl and refrigerate for at least 30 minutes or up to 2 hours for more flavor.
3. Prepare the Vegetables: While the steak marinates, cut the bell pepper, onion, and tomatoes into the desired sizes.
4. Soak Wooden Skewers: If using wooden skewers, soak them in water for at least 30 minutes to prevent burning on the grill.
5. Preheat the Grill: Preheat your grill to medium-high heat (about 400-450°F).
6. Assemble the Skewers: Thread the marinated steak and vegetables onto the skewers, alternating between meat and vegetables for a colorful presentation.
7. Grill the Kabobs: Place the skewers on the grill and cook for about 10-15 minutes. Turn them occasionally to ensure even cooking until the steak reaches your desired doneness (medium-rare is about 130°F, medium is 140°F).
8. Remove and Rest: Once cooked, remove the kabobs from the grill and let them rest for a few minutes. This helps the juices redistribute within the meat.
9. Serve: Serve the kabobs warm with your favorite sides, such as rice, salad, or grilled bread.
