Place cubed beef in a sealable plastic bag. Add 2 tablespoons olive oil, lemon juice, Italian seasoning, minced garlic, salt, and ground black pepper. Expel excess air, seal the bag, and massage marinade into the beef until evenly coated.

Refrigerate marinating beef for a minimum of 30 minutes, preferably overnight, turning bag occasionally to ensure even absorption.
03 -
Thread marinated beef onto skewers, alternating with pieces of red bell pepper, red onion, and zucchini until all ingredients are used.

Preheat a grill pan or outdoor grill over medium-high heat for 4 to 5 minutes. Lightly brush the grill grates with the remaining olive oil when hot and shimmering.

Grill beef kebabs for 8 to 10 minutes per side, or until the beef reaches an internal temperature of 68 °C for medium. For well-done, cook 1 to 2 minutes more per side or until reaching 71 °C. Rotate skewers as needed for even cooking.

To cook in the oven, place assembled skewers on a baking tray and broil at high heat for 4 to 5 minutes per side until beef is cooked through and lightly charred.

Remove skewers from heat. Let rest a few minutes to allow juices to redistribute. Serve with Greek rice, pita bread, lemon roasted potatoes, Greek salad, and tzatziki sauce.
