In a medium bowl, whisk together ¼ cup of olive oil, ¼ cup of soy sauce, 2 tablespoons of balsamic vinegar, 4 minced garlic cloves, and a pinch of salt and pepper.

Cut 1.5 pounds of sirloin steak into 1-inch cubes and add them to the marinade. Ensure each piece is thoroughly coated.

If using wooden skewers, soak them in water for about 30 minutes prior to grilling.

Once the steak has marinated, alternate threading the marinated steak and colorful vegetables onto the soaked skewers.

Preheat your grill to medium-high heat, aiming for around 400°F.

Carefully place the assembled kabobs on the preheated grill. Cook for 10 to 12 minutes, turning occasionally.

Once cooked to your liking, remove the kabobs from the grill and let them rest for about 5 minutes before serving.
