Mix all spices in a zip-type bag. Oil both sides of meat. Lightly coat both sides of oiled meat with seasonings. Put a layer of sliced onions in bottom of bag, and then put a layer of seasoned meat. Add another layer of sliced onion on top of meat. Repeat until meat is gone or bag is full. Squeeze all excess air out of bag and seal. Put bag in refrigerator for three to five days.
I gave this 4 stars because it was a little dry but that may be because I used 1/4 inch pork chops in place of the 1/2 inch steaks. The flavor was wonderful can't wait to get that steaks and make it to specs.
