Grilled Steak Skewers with Colorful Vegetables

In a large bowl, thoroughly mix all ingredients for the marinade (olive oil, soy sauce, red wine vinegar, honey, mustard, and Worcestershire sauce).

Add the diced beef fillet and mix thoroughly with the marinade. Cover and let marinate in the refrigerator for at least one hour.

Preheat the grill or a grill pan to high heat. Cut the prepared vegetables into bite-sized pieces and lightly brush with a little olive oil.
