Wash the steak slices and dry them well with paper towels.

In a small bowl, mix the olive oil, chopped fresh herbs (thyme, parsley, coriander, rosemary), crushed garlic, lemon juice, Dijon mustard, salt, and black pepper. Stir the ingredients well until combined.

Place the beef pieces in a deep bowl and pour the herb marinade over them. Make sure all the pieces are well coated.

Gently massage the marinade into the meat for about 15 minutes.

Cover the bowl tightly and place the meat in the refrigerator for at least 30 minutes.

Preheat the grill well over medium-high heat.

Take the meat out of the refrigerator and let it sit for a few minutes to come closer to room temperature before grilling.

Place the marinated steak pieces on the hot grill. Grill the steak for 3-5 minutes on each side, depending on your desired level of doneness.

After grilling, place the steak on a clean plate, cover it with aluminum foil, and let it rest for 5-10 minutes before serving.

Serve the herb-grilled steak hot with grilled vegetables or a fresh salad.
