Tender, juicy chunks of beef are marinated for maximum flavor, then threaded onto skewers with colorful vegetables and grilled until perfectly charred.
Whisk together the olive oil, vinegar, soy sauce, Worcestershire sauce, garlic, oregano, paprika, sugar, and black pepper in a medium bowl. Add steak and stir to coat.
Cover with plastic wrap and refrigerate for 4 to 6 hours, giving it a stir a time or two during the marination period.
Turn the grill on to medium-high heat.
Arrange the steak and vegetables on skewers. Brush with marinade and sprinkle lightly with salt.
Grill for about 15 minutes, brushing with marinade halfway through and turning to cook all sides evenly.
Notes
Tenderloin, NY Strip Steak, or Ribeye Steak can be used instead of sirloin.
