You will need..
Corn on the cob
Canola oil or olive oil
Place the corn cobs on individual sheets of aluminum foil.
Rub them with olive oil or spray canola oil on them.
Sprinkle with spices. I used garlic salt and pepper.
Throw on the grill, and rotate every couple minutes.
They take about half hour. Check every once in awhile to make sure their not burning.
Unwrap and enjoy!
