STEP 1/5
For steak tenderloin, tap the edge with a meat hammer. Grind the onion on a grater to make the marinated seasoning, then marinate the tenderloin patted with a meat hammer (at least 1 hour in the refrigerator). I usually let it marinate the day before and then eat it the next day).
STEP 4/5
Place grill on the pan, place paper foil on top, and bake for 15 to 20 minutes (choose time to suit your taste of meat) and turn it upside down in the middle.
