For the beef tenderloin steak stuffed with vegetables, first carefully cut a pocket crosswise into the beef tenderloin steaks.
Wash and finely chop the parsley. Clean the vegetables, tear them finely with a vegetable slicer, sauté them in a pan with oil for a few minutes if necessary, add the chopped parsley, deglaze with a little balsamic vinegar bianco and season with salt and pepper.
Stuff the vegetables into the pockets of the steaks, wrap the steaks with strips of bacon, tying with spaghetti if necessary so that the bacon holds well.
Prepare the grill for direct grilling with high heat.
Season cut sides of steaks with salt and pepper, then grill on direct heat for about 3 minutes on each side.
After grilling, let the beef fillet steak stuffed with vegetables rest wrapped in aluminum foil for about 5 minutes.
